If the surface area of an orange is 616 cm2 what is its radius?

1 answer:

8 0

9514 1404 393

Answer:

7.0 cm

Step-by-step explanation:

The relationship between radius and area of a sphere is ...

A = 4πr²

Then the radius as a function of area is ...

r = √(A/(4π)) = (√(A/π))/2

For an area of 616 cm², the corresponding radius is ...

r = (√(616/π))/2 ≈ 7.0 cm . . . . radius of the orange
