A cylindrical beaker has a height of 16 cm and a diameter at its bottom of 10 cm. What is its volume? Give your answer to 2 decimal places.
As the beaker is a cylinder, we know the formula of its volume is (pi x (radius)2) x height.
Since the radius = 1/2 diameter and the diameter = 10 cm, the radius = 5 cm.
We know the height is 16 cm.
So the formula for the volume becomes:
(pi x (5)2) x 16 = 1256.63706144 cm3
If we round this to 2 d.p. it becomes:
1256.64 cm3 to 2 d.p.
