* Answer Type Questions (Slab-D)
Find the volume of a right circular cone with
(1) Radius 4 m and height 9 m​

Answer 1

Step-by-step explanation:

1/3*22/7*8*9

22*8*9/7

Answer 2

Answer:

$\boxed{\sf Volume \ of \ a \ right \ circular \ cone = 150.86 \ m^{3}}$

Given:

Radius (r) = 4 m

Height (h) = 9 m

To Find:

Volume of right circular cone

Step-by-step explanation:

$\sf Volume \ of \ right \ circular \ cone = \frac{1}{3} \pi r^{2} h \\ \\ \sf = \frac{1}{3} \times \frac{22}{7} \times {(4)}^{2} \times 9 \\ \\ \sf = \frac{1}{ \cancel{3}} \times \frac{22}{7} \times 16 \times 3 \times \cancel{3} \\ \\ \sf = \frac{22}{7} \times 16 \times 3 \\ \\ \sf = \frac{1056}{7} \\ \\ \sf = 150.86 \: {m}^{ 3}$

Additional information:

Volume of 3D figure:

$\sf Cuboid = Length \times Breadth \times Height$

$\sf Cube = Side^{3}$

$\sf Sphere = \frac{4}{3} \pi r^{3}$

$\sf Hemisphere = \frac{2}{3} \pi r^{3}$

$\sf Cylinder = \pi r^{2} h$
