Which Of The Follwong Is CLOSEST To The Area Of The Shaded Part Of Circle V?

Answers

Answer 1

Answer:

A

Step-by-step explanation:

The entire circle has an area of pi * r^2

r = 10

pi = 3.14

Area = 3.14 * 10^2

Area = 314 cm^2

But that is the whole circle. What is shaded is 1/4 of the circle which 314/4

which = 78.5 cm^2

Answer: A

Answer 2

Answer:

A) 78.5 cm^2

Step-by-step explanation:

1. To find the shaded part of the circle (1/4), we can use a formula similar to the one we use to find the area of a whole circle, but in this case, for the 1/4 part that's shaded: [tex]\frac{1}{4} \pi r^2[/tex]. Keep in mind that pi is approximated to 3.14.

2. (Solving)

Step 1: Plug in the values.

[tex]\frac{1}{4}(3.14)(10^2)[/tex]

Step 2: Simplify.

[tex]\frac{1}{4}(3.14)(100)[/tex] [tex]0.785(100)[/tex] [tex]78.5[/tex] 78.5 cm^2

Therefore, the answer is A) 78.5 cm^2.

for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each.How much did the school spend in all?

Answers

Answer: To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.

Step 1:

Sum of  one sandwich= 4.60 dollar

sum of 47 sandwiches= 47×4.60 =216.2dollars

Step 2:

Sum of one chip=1.25 dollar

sum of 39 bags of chips=39×1.25= 48.75dollars

step 3: sum up the sum of sandwiches and that of the chips

216.2 + 48.75 =264.95dollars

What is 7/8 divided by 2/8

Answers

Answer:

7/8 ÷ 2/8 = 3 1/2

Step-by-step explanation:

When we divide two fractions, such as 7/8 ÷ 2/8, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

The quotient obtained from the division of given fractions is 7/2.

Given that, 7/8 divided by 2/8.

Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.

Here, 7/8 ÷ 2/8

= 7/8 × 8/2

= 7/2

Therefore, the quotient obtained from the division of given fractions is 7/2.

Let's first find BD. Triangle ADB is a right triangle with hypotenuse AB. By definition of sine ( or by theorem, they're equivalent) [tex]{BD \over 20} = sin 54.[/tex], hence BD= 16.18.

As usual, triangle MJL is a right triangle with sides MJ and LJ. By definition of tangent [tex] {{JL} \over 14} = tan 51 [/tex]. Follows that JL = 14.81. Now, similarly, trinagle JLK is a right triangle, with hypotenuse JL. From the definition of sine, as before,[tex]{KL \over 14.81} = sin 72.[/tex].

Step-by-step explanation:

A tractor can plant a field at a rate of 2.5 acres per 5 minutes. If a mammoth farm measuring 4 square miles needs planting, how long will it take in hours to plant the field? There are 640 acres in a square mile. Determine your answer to the nearest hour. If the tractor can run 8 hours a day, what is the minimum number of days it will take to plant the farm?

Answers

The time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.

The minimum number of days taken by the tractor when working 8 hours a day is 11 days.

What is the area?

The area is the total surface occupied within the boundary of the figure.

How to solve the question?

In the question, we are given that a tractor can plant a field at a rate of 2.5 acres per 5 minutes.

We are asked the time taken by the tractor to plant a field having an area of 4 square miles.

First, we convert the area of the field from sq. miles to acres using the conversion rate, 1 square mile = 640 acres,

Thus, the area of the field = 4 sq. miles = 4*640 acres = 2560 acres.

Time taken to plant 2.5 acres is given to be 5 minutes.

Thus, the time taken to plan 1 acre = 5/2.5 = 2 minutes.

Thus, the time taken to plant the field having an area of 2560 acres = 2560*2 minutes = 5120 minutes = 85.33 hours =  85 hours and 20 minutes.

Thus, the time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.

The time for which the tractor can run daily is 8 hours.

Thus, the number of days taken by the tractor to plant the field = 85.33/8 = 10.66625, or 11 days.

Thus, the minimum number of days taken by the tractor when working 8 hours a day is 11 days.
