Answer 2

`\text{The surface area is }2123.72\thinspace units^2`

Explanation:

Given the radius of sphere which is 13 units

we have to find the surface area of sphere.

Radius=13 units

`\text{The surface area of sphere =}4\pi r^(2)`

`=4* (22)/(7)* (13)^2=2123.716\sim 2123.72`

`\text{The surface area is }2123.72\thinspace units^2`
