Question

Find the volume of the cylinder and cone, then add them together.

Answer 1

`Total \: \: \: Volume = (88+176) {cm}^(2) \\ \\ = 264 {cm}^(2) .`

Answer 2

★ Volume of cylinder :-

• V = πr²h

Here,

• r is radius
• h is height

We have :

• r = 2cm
• h = 7cm

Substituting the values :

> V = π (2 × 2) × 7

> V = 4π × 7

> V = 28π

★ Volume of cone :-

• V = ⅓ π²h

We have :

• r = 2cm
• h = 6 cm

Substituting the values :

> V = ⅓ × π × (2 × 2) × 6

> V = ⅓ × π × 4 × 6

> V = ⅓ × π × 24

> V = 8π

★ According to the question :-

Adding them together,

> Total Volume = 8π + 28π

> Total Volume = 36π
