Answer:
Explanation:
The formula for calculating the volume of a cylinder is expressed as
Volume = πr^2h
where
r is the radius of the cylinder
h is the height of the cylinder
π is a constant whose value is 3.14
From the information given,
V = 90
r = 3
By substituting these values into the formula,
90 = 3.14 x 3^2 x h
90 = 28.26h
Dividing both sides by 28.26,
90/28.26 = 28.26h/28.26
h = 3.2 cm
