What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
We have to find the volume of a cone with a radius of 3 and a height of 19.
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
r=3 and h=19
We have to find the space in the cone with radius 3 and height 19.
The formula for volume of the cone is V=1/3πr²h
We have to plug in the r and h values in formula.
V=1/3×3.14×(3)²×19
=1/3×3.14×9×19
=536.94/3
=179.07 cubic units
Hence, the volume of a cone with a radius of 3 and a height of 19 is 179.07 cubic units.

How can you find f(2) if f(x) = -3x2 – 7?
Answer:
-3(2) x 2 -7 = -6x2-7 =-19
Step-by-step explanation:
The value of f(2) for the given function f(x) = -3x² – 7 will be -19.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
As per the given function,
f(x) = -3x² – 7
Put x = 2
f(2) = -3(2)² - 7
f(2) = -2(4) - 7
f(2) = -8 - 7 = -15
Hence "The value of f(2) for the given function f(x) = -3x² – 7 will be -19".

The areas of the squares adjacent to two sides of a right triangle are 32 units^2 2 squared and 32 units^2 Find the length, xxx, of the third side of the triangle.
Answer:
8 units
Step-by-step explanation:
If the area of the squares are 32 units^2, we have that:
Area = Side * Side
Side^2 = 32
Side = sqrt(32) = 5.657 units
So as the squares are adjacent to two sides of the triangle, we have that the triangle has two sides of 5.657 units
As it is a right triangle, we can use the Pythagoras' theorem:
c^2 = a^2 + b^2
c^2 = 5.657^2 + 5.657^2
c^2 = 64
c = 8 units

what is the correlation coefficient for the data in the table -0.93,-0.27,0.27.0.93
The answer to this question is the letter D.
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
How to find the correlation coefficient for the data table -0.93,-0.27, 0.27, 0.93?
This is because the correlation coefficient focuses on the linear relationship between two variables.
numbers between -1 and 1 should be one of the values related to the bill. As you can the letter D is the closest and most realistic answer.

Los alumnos de una clase han formado 4 equipos para hacer un mural en una pared del patio. Los equipos tienen 8,7, 10 y 5 componentes. Si la pared mide 12 m de largo, ¿cuántos metros de pared le corresponde a cada equipo para que sea proporcional al número de componentes?
Answer:
8 - 3.2m
10- 4m
7- 2.8m
5- 2m
Step-by-step explanation:
Aquí, podemos hacer los componentes en forma de relaciones para conocer la longitud equivalente de cada uno de los componentes a la longitud total de la pared.
Ahora usando los componentes en forma de proporciones, tenemos 8: 7: 10: 5. sumando todos los componentes juntos, tenemos; 8 + 7 + 10 + 5 = 30.
Para 8, tenemos 8/30 * 12 = 3.2 metros
para 7, tenemos 7/30 * 12 = 2.8 metros
Para 10, tenemos 10/30 * 12 = 4 metros
para 5, tenemos 5/30 * 12 = 2 metros

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number = c
We can make an expression as,
c - 13 = -2
Now,
Solve for c.
c - 13 = -2
Add 13 on both sides.
c = -2 + 13
c = 11
Thus,
The value of c is 11.

what is s+53=g so g=68 so how old is sweet age add
Answer:
s = 15
Step-by-step explanation:
Using the given information to solve for s, the work would look something like this:
s + 53 =g, g=68
s + 53 = 68 (Subtract 53 from both sides to get s by itself)
53 - 53 = 0, 68 - 53 = 15
s = 15
Therefore, s is equal to 15
Hope this helps! Have a good rest of your day!
Answer:
15
Step-by-step explanation:
This is very simple, first we write the equation, s+53=g, and plug 68 into "g", so now we have s+53=68. Subtract both sides, s+53-53=68-53, and this equals 15 years of age

Terrence gets a loan with a $50 processing fee. The loan is for $700 with an interest rate of 8% for one
year.
The interest on the loan is
The APR on this loan is
Answer:
15.14%
Step-by-step explanation:
The formula for APR is stated thus:
APR=fees+interest/principal/n*365*100
principal is the loan amount of $700
fees is the processing fees on the loan which is $50
interest amount=principal*interest %=$700*8%=$56
n is the number of days of the loan which is a year i.e 365 days
APR=($50+$56)/$700/365*365*100
APR=$106/$700/365*365*100
APR=0.151428571 /365*365*100
APR=0.151428571 *100=15.14%
The annual percentage rate on the loan is 15.14% which represents the actual cost on the loan not just the interest cost of 8% annually
