Question

A right triangle ABC with sides 5 cm 12 cm and 13 cm is revolved about the side 12 cm find the volume of the solid so obtained.
​

Answer 1

AnsWer:-

Volume of the solid(cone) is 100πcm³.

Step-by-step explanation:

Given:-

• Sides of the traingle are 5 cm 12 cm and 13 cm.
• The ∆ABC is revolved around the side 12cm.

Need to find:-

• The volume of the solid(cone).

EXPLANATION:-

Height of the right triangle = 12cm

Radius of the right triangle = 5cm

As we know that,

Volume of the solid = 1/3πr²h

Putting values in this formula,

We get;

Volume of the solid(cone) = 1/3×π×5×5×12

=> 100πcm³

Hence,the volume of the solid(cone) is 100πcm³.
