The formula below gives A, the area of a circle with radius r. 

A(r) = r2 

To the nearest hundredth, what is the value of A(8)? (Use 3.14 for .)

Answer 1

the correct answer is A

Answer 2

A(r) = πr²

A(8) = π*8*8

A(8) = 64π

A(8) ≈ 64*3.14 ≈ 200.96

Option (A) is the answer.

Hope this explains it.
