Answer 2

Given :

✰ Radius and cylinder = 7cm

✰ Height of cylinder = 30cm

To Find :

✰ Volume and Total surface area of cylinder

Solution :

✰ As in the question Radius and height of cylinder is given. Firstly we will find volume of cylinder by Using formula πr²h. Then Total surface area of cylinder 2πr(h + r). We will fill the value of radius and height We can easily find the volume and surface area of the cylinder.

Volume of cylinder = πr²h

Where,

• Radius (r) = 7cm

• Height (h) = 30cm

→ 22/7 × (7)² × 30

→ 22/ 7 × 49 × 30

→ 22 × 7 × 30

→ 4650cm³

T.S.A of cylinder = 2πr(h + r)

→ 2 × 22/7 × 7( 7 + 30)

→ 2 × 22 × 37

→ 44 × 37

→ 1628cm²

∴ Volume of cylinder is 4650cm³

∴ T.S.A of cylinder is 1628cm²
