Question

What is the surface area of a sphere with a radius of 11 units? Leave it in pi

Answer 1

`\text{Area of sphere is }484\pi units^2`

Explanation:

Given the radius of sphere 11 units

we have to find the surface area of sphere

Radius=11 units

As area of sphere can be calculated as

`\text{Area}=4\pi r^2`

`=4\pi (11)^2=484\pi units^2`

`\text{Area of sphere is }484\pi units^2`

Answer 2

The answer is 484 π units²

The area of a sphere with radius r is:
A = 4πr²

We have:
A = ?
r = 11 units

So:
A = 4π * 11²
A = 4π * 121
a = 484 π units²
