Me , i don’t remember how to do this

9 ft

Step-by-step explanation:

V = 4/3 pi r^3

We know the volume is 972 pi

Substituting in

972 pi = 4/3 pi r^3

Dividing both sides by pi

972 pi/pi = 4/3 pi/pi r^3

972 = 4/3 r^3

Multiply both sides by 3/4

3/4 *972 = 3/4 *4/3 r^3

729 = r^3

Take the cube root of each side

(729)^1/3 = (r^3)^1/3

9 =r

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
