Question 754249
Larry is building a cylindrical silo that must have a volume of 65m3. the height of the silo must be 6 meters, what is the radius?

formula for the volume of a cylinder is 

V = pi*r^2*h

we have

65 = (22/7)*r^2*6      note that pi is represented by (22/7)

multiply both sides of = by 7

455 = 22 *r^2 *6

455 = 132 * r^2

divide both sides of the = by 132

r^2 = 455/132 and

r = sqrt(455/132) = 1.86 m
