Answer:

A) 78.5 cm^2

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:
(1)/(4) \pi r^2. Keep in mind that pi is approximated to 3.14.

2. (Solving)

Step 1: Plug in the values.


  • (1)/(4)(3.14)(10^2)

Step 2: Simplify.


  • (1)/(4)(3.14)(100)

  • 0.785(100)

  • 78.5
  • 78.5 cm^2

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

Answer:

A

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
