Question

A playground area is circular with a diameter of 32 feet. What is the area of the playground round your answer to the nearest tenth

Answer 1

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

Answer 2

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