Question

What is the area of the figure below
10cm

Answer 1

A= 100 + 20π. or 162.832

Explanation:

you first need to find the radius of the half circles with would be half of 10

so r = 5

and the circumstance equation is

c = 2πr

c = 2π(5)

c=10π

but circumference is calculating for a whole circle and you have 4 half circles. 4 half circles make 2 full circles.

2(10π)= 20π

now find the area of the square

10 × 10 = 100

put them together

100 + 20π
