Question

Find the volume of a cone with a height of 9 cm and a base diameter of 10 cm.Use the value 3.14 for it, and do not do any rounding.Be sure to include the correct unit in your answer.

Answer 1

Volume of a cone (V) = 1/3 π r^2 h

Where:

r= radius

h= height = 9 cm

π= 3.14

radius = diameter /2 = 10 /2 = 5 cm

Replacing:

V = 1/3 (3.14) (5)^2 (9) =235.5 cm3
