Question

A right circular cone of diameter is 3 and height is 1. find its volume?

Answer 1

Step-by-step explanation:

volume of right circular cone = 1/3 π r² h

diameter = 3

radius = diameter/2

= 3/2

= 1.5

height = 1

volume =

$= \frac{1}{3} \times \frac{22}{7} \times 1.5 \times 1.5 \times 1 \\ = \frac{1}{2} \times \frac{22}{7} \times 1.5 \times 1 \\ = \frac{11}{7} \times 1.5 \times 1 \\ = \frac{16.5}{7} \\ = 2.35 \: {units}^{3}$
