the area of a circle is A=[tex] \pi [/tex]*[tex] R^{2} [/tex]
we can find the radius by deviding the diameter by 2
32/2=16
A=[tex] \pi [/tex][tex] 16^{2} [/tex]
A=3.14*256
A=803.84 feet

The formula for area of a circle is radius × radius × [tex] \frac{22}{7} [/tex]
So first, find the radius:32 ÷ 2 = 16 ft
Then multiply 16 × 16 × [tex] \frac{22}{7} [/tex] = [tex] 804\frac{4}{7} [/tex] as your answer.
Don't forget your unit and square in your answer
