A sphere has a diameter of 12.5 inches. What is the surface area of the sphere? 50π in² 156.25π in² 625π in² 2604.17π in²

Advocard [28]

Hello!

To find the surface area of a sphere you use the equation

$A = 4 \pi r^{2}$

A is surface area
r is radius which is half the diameter

Put in the values you know

$A = 4 \pi 6.25^{2}$

Square the number

$A = 4 \pi 39.0625$

Multiply the 4 and the 39.0625

$A = 156.25 \pi$

The answer is $B) 156.25 \pi in^{2}$

Hope this helps!
