Question

What is the circumference of a circle if its area is 64.

(giving 25 points :))

Answer 1

Answer is below.

Explanation:

Using the formula for circumference using area, we can plug in the area and solve backwards for the circumference.

Answer 2

28.35

Explanation:

Area = pi × r²

64 = 3.14 × r²

r² = 64/3.14

r = 4.514661184

Circumference = 2 × pi × r

2 × 3.14 × 4.514661184
