Question

PLEASE hep?? :)

Answer 1

well, so suppose those 2 quarters of a circle are from the whole circle of radius 10. Then The area of that circle would be pi*r^2= pi*10^2=100pi.
Half of that would be 50pi, so the area of the white regions is 50pi.

Answer 2

I got that from the fact that two quarters of a circle make a semicircle. So now, subtract 50pi from the area of the rectangle which is:
(10+10)*10=20*10=200

Answer 3

200-50pi = 200-50*3.14 which is about 43

Answer 4

square feet

Answer 5

FINAL ANSWER? THANK YOU SO MUCH :)

Answer 6

Whoops, sorry abiut the caps!

Answer 7

43

Answer 8

At=A(rectangle) - A[1/2 circle]
= LxW - 1/2(pi r^2)
=10x20 - 1/2(PIx10^2)
= 200-157
=43 sq ft

Answer 9

did that help maybe

Answer 10

yes
