Question

Find the radius of a metal container that is 28 centimeters tall an a volume of 8,800 cubic centimeters use pie =3 1/7

Answer 1

Oh well, pi = 22/7
pi r^2 * h = 8800
(22/7) r^2 * 28 = 8800
4 r^2 = 400
r^2 = 100
so r = sqrt 100
what else ?

Answer 2

pi doesnt equal 22/7. most people think it does but its actually the closest fraction to pi. Bc pi is an irrational number, it is impossible to put it in a fraciton other that pi/1.
