Acylinder has a volume of 225π inches3 . what is its height, if its radius is 10 inches? a) 2.25 inches b) 22.5 inches c) 2.25 π inches d) 0.716 inches

The formula for the volume of a cylinder is

... V = π·r²·h

where r is the radius and h is the height.

Filling in the given numbers, we have

... 225π in³ = π·(10 in)²·h

Dividing by the coefficient of h, we get

... (225π in³)/(100π in²) = h

Cancelling common factors, gives

... 2.25 in = h

The appropriate choice is

... A) 2.25 inches

the monthly balance will be $75,000
