Question

A cylinder of radius 0.7cm and height 2 cm is removed from a cone of radius 1.4 cm and height 6 cm. find the volume of the remaining part of the cone

Answer 1

Answer:

Volume of remaining part = volume of cone - valoume of cylinder

$(1 \div 3)\pi {r}^{2}h - \pi {r}^{2} h$

Step-by-step explanation:

( 1/3 * 22/7 * 1.4 * 1.4 * 6) - 22/7 * 0.7 *0.7 * 2

= 12.32 - 3.08

= 9.24 cm cube
