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

allochka39001 [22]

Answer:

2,122.64 square units or $676 \pi$ units squared

Step-by-step explanation:

The surface area of a sphere can be found using the formula $A=4\pi r^2$ . Since the radius is 13 units, substitute r=13.

$SA=4\pi r^2\\SA = 4 \pi (13)^2\\SA = 4 \pi *169\\SA = 2122.64$

Without multiplying 3.14 for $\pi$ , the answer is

$SA = 169*4 \ pi\\SA = 676 \pi$
