QUESTION 9 1 POINT1The Kugel ball at Bob Devaney Sports Center is a big granite sphere with a radius of 1.2 meters. Find its a. volume and b.surface area. Use 3.14 for T. Round the answers to the nearest hundredth.Provide your answer below:volumecubic meters, surface area =square meters

Answer 1

We are to look for the volume and also the surface area of a sphere.

Given:

radius r = 1.2 meters

π = 3.14

(a) volume of the sphere:

Formular for volume of a sphere:

V = 4/3πr³

Substituting values into the formular

V = 4/3 * 3.14 * 1.2³

V = 3/4 * 3.14 * 1.728

V = 7.23456

V = 7.235 cubic meters

Therefore, the volume of the sphere is 7.235 cubic meters

(b) surface area of the sphere

formular for the surface area of a sphere is:

SA = 4πr²

input values into the formular:

SA = 4 * 3.14 * 1.2²

SA = 4 * 3.14 * 1.44

SA = 18.0864

SA = 18.086 square meters

Therefore, the surface area of the sphere is 18.086 square meters
