Answer:
18.84
Explanation:
the formula to find the area of circle is: A = π⋅r^2
the area is already stated so,
= 28.26 = π⋅r^2
= 28.26π = r^2
= 8.995437 = r^2
= √8.995437 = r
= 2.999239=r
we have found that the radius is 2.999239 and the formula for circumference of a circle is: π⋅d
2.999239⋅2 = 5.99848 (multiply by 2 to get the diameter)
5.99848⋅π = 18.84478
so the answer is 18.84
