Question

Find the volume of a party hat shaped like a cone with a radius 8 centimeters and height 9 centimeters round your answer to two decimal places

Answer 1

We have to apply the next formula:

Volume of a cone= 1/3 π radius^2 height = 1/3 π r^2 h

We have:

radius= 8 cm

height= 9cm

Replacing in the formula:

V = 1/3 π (8)^2 (9)= 1/3 π (64) 9 = 603.19 cm2

Volume = 603.19 square centimeters
