What is the volume and total surface area of a sphere with the radius 2.25in?

Step-by-step explanation:

The formula for determining the volume of a sphere is expressed as

Volume = (4/3) πr³

Where

r represents the radius of the sphere.

π is a constant whose value is 3.14

From the information given,

radius = 2.25 inches

Volume = 4/3 * 3.14 * 2.25³

Volume = 47.69 inches³

The formula for determining the total surface area of a sphere is expressed as

Total surface area = 4πr²

Therefore

Total surface area = 4 * 3.14 * 2.25²

= 63.9 inches²

The volume is 15.89625
