Question

find the volume of a cone having radius 10 m and height 20 m.​

Answer 1

Right circular cone

Right circular coneV≈2094.4m³

Right circular coneV≈2094.4m³r Radius

Right circular coneV≈2094.4m³r Radius 10

Right circular coneV≈2094.4m³r Radius 10m

Right circular coneV≈2094.4m³r Radius 10mh Height

Right circular coneV≈2094.4m³r Radius 10mh Height 20

Right circular coneV≈2094.4m³r Radius 10mh Height 20m

Answer 2

$\large{ \boxed{ \sf \: Volume \: of \: a \: cone = \frac{1}{3} \pi {r}^{2} h}}$

Radius = 10 m

Height = 20 m

Here,

$\sf = \frac{1}{3} \times \frac{22}{7} \times {(10)}^{2} \times 20 \\ \\ \sf = \frac{22}{21} \times 100 \times 20 \\ \\ \sf = \frac{44000}{21} = 2095.23 \: m \: (approx)$
