Answer:
D.~ 34.2~cm^2
Step-by-step explanation:
An arc measure of 20 degrees corresponds to a central angle of 20 degrees.
Area of sector of circle
area = \dfrac{n}{360^\circ}\pi r^2
where n = central angle of circle, and r = radius
area = \dfrac{20^\circ}{360^\circ}\pi (14~cm)^2
area = \dfrac{1}{18}(3.14159)(196~cm^2)
area = 34.2~cm^2

find the missing letter which is N.the length is 25 in and the perimeter is 86 in
Answers
Answer:
Step-by-step explanation:
length = 25 in
Perimeter = 86 in
2*(length + width) = 86
2*(25 + N) = 86
Divide both sides by 2
25 + N = 86/2
25 + N = 43
Subtract 25 from both sides
25 + N - 25 = 43 - 25
N = 18

write the equation of circle b with center B(-2,3) that passes through (1,2)
Answers
Answer:
[tex](x+2)^2 + (y-3)^2 = 10[/tex]
Step-by-step explanation:
The standard equation for circle is
[tex](x-a)^2 + (y-b)^2 = r^2[/tex]
where point (a,b) is coordinate of center of circle and r is the radius.
______________________________________________________
Given
center of circle =((-2,3)
let r be the radius of circle
Plugging in this value of center in standard equation for circle given above we have
[tex](x-a)^2 + (y-b)^2 = r^2 \ substitute (a,b) \ with (-2,3) \\=>(x-(-2))^2 + (y-3)^2 = r^2 \\=>(x+2)^2 + (y-3)^2 = r^2 (1)[/tex]
Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.
Plugging in the point (1,2 ) in equation 1 we have
[tex]\\=>(x+2)^2 + (y-3)^2 = r^2 \\=> (1+2)^2 + (2-3)^2 = r^2\\=> 3^2 + (-1)^2 = r^2\\=> 9 + 1 = r^2\\=> 10 = r^2\\=> r^2 = 10\\[/tex]
now we have value of r^2 = 10, substituting this in equation 1 we have
Thus complete equation of circle is [tex]=>(x+2)^2 + (y-3)^2 = r^2\\=>(x+2)^2 + (y-3)^2 = 10[/tex]

On a distant planet, a 20º central angle intercepts an arc of 4067 miles. What is the radius of the planet at its equator?
The radius of the planet is
miles. (Simplify your answer.)
Answers
Answer: 11,682.4 miles
Step-by-step explanation:
We can think the planet as a circle:
if we have a circle of radius R, and an arc of A degrees in the circle, the lenght of the arc is:
L = (A/180°)*3.14*R
Here we know that:
L = 4076 miles
A = 20°
Then:
4076mi = (20/180)*3.14*R = 0.3489*R
R = 4076mi/0.3489 = 11,682.4 miles
keisha estimates 259 + 372 by rounding each number to the nearest 10 what is keisha estimate of the sum
Answers
Answer:
630
Step-by-step explanation:
260+370
This question is based on the rounding off rule. Therefore, Keisha estimate of the sum is 630.
Given:
Keisha estimates 259 + 372 by rounding each number to the nearest 10.
We need to determined the what is Keisha estimate of the sum.
According to the question,
By using the round- off rule as follows:
If the numbers are 5, 6, 7, 8, or 9, round the number up.Example: 38 rounded to the nearest ten is 40. ...
If the number are 0, 1, 2, 3, or 4, round the number down.Example: 33 rounded to the nearest ten is 30.
First we rounding off the 259,
From the first rule, 259 is round the number up.
Therefore, we get the value 260.
Now,rounding off the 372,
From the second rule, 372 is round the number down.
Therefore, we get the value 370.
Now, sum up the both numbers,
260 +370 = 630
Therefore, Keisha estimate of the sum is 630.
