Question

Practice set 7.1
1. Find the volume of a cone if the radius of its base is 1.5 cm and its perpendicular
height is 5 cm. with meathod
​

Answer 1

Step-by-step explanation:

r=1.5

h=5cm

Volume of cone =

$\frac{1}{3} \pi {r}^{2} h$

$\frac{1}{3 } \times \frac{22}{7} \times 1.5 \times 1.5 \times 5 \\ \\ = \frac{82.5}{7} \\ \\ = 11.785$
