Question

3. a) If the radius of a spherical orange is 3.5 cm, find its surface area and volume
​

Answer 1

Surface Area = 153.94

Volume= 179.59

Explanation:

To find the surface area take the equation

A= 4πr^2 and plug in the radius (3.5)

4·π·3.52≈153.93804

The surface area rounded to the nearest hundredth is 153.94

To find the volume take the equation V=(4/3) πr^3

plug in your radius

(4/3)·π·3.5^3≈179.59438

Volume to the nearest hundredth = 179.59
