Question

A spherical globe has a radius of 9 inches. What is the surface area of the globe to the nearest hundredth of a square inch? (Use calculator t number.)

Answer 1

`\huge\boxed{\sf SA \approx 1017.88\ in.\²}`

Explanation:

Given data:

Radius = r = 9 in.

Surface area of sphere = 4πr²

Solution:

So,

Using π = 3.14

SA of sphere = 4(3.14)(9)²

SA = 4(3.14)(81)

SA ≈ 1017.88 in.²

So, the surface area of the sphere is 1017.88 in.².
