Question

What is the surface area of a sphere with a radius of 13

Answer 1

Answer:

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

Step-by-step explanation:

Given the radius of sphere which is 13 units

we have to find the surface area of sphere.

Radius=13 units

$\text{The surface area of sphere =}4\pi r^{2}$

$=4\times \frac{22}{7}\times (13)^2=2123.716\sim 2123.72$

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

Answer 2

$Formula: 4\pi r^{2}$

$The\:Correct\:Answer\:Is\:A=2123.72$

$Explanation: A=4\pi r^2=4*\pi *13^2=2123.71663$
