Find the radius of a sphere with surface area of 100 pi square centimeters

The surface area of a sphere = 4πr²

4πr²=100π

Dividing both sides by 4π,

r² = 100π÷4π = 25

r² = 25

Taking the square root on both sides, 

r = 5 centimeters  

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3

Yes you do, so £1973.09 - £1473.50 = £499.59 so tim overpaid £499.59 .hope this ; )
