oohh, a

anonymous · Answer

Jeeze

anonymous · Answer

15.7 divided by 2

anonymous · Answer

Why don't you just use a calculator

bookworm14 · Answer

this is a fourth of a circle with 2 straigh sides that equal 5 inches each so you only need 1/4 of your circumference +10

2*5*pi =31.4 (this is for a WHOLE circle)
divide it by 4 because you only need one fourth
31.4 / 4= ? you tell me

anonymous · Answer

it is a
