Question

the height of cylender is 14cm and the curved surface area is 220cm. find the volume




please give the answer​

Answer 1

Given :

• Height of the cylinder = 14 cm

• Curved surface area = 220 cm

To Find :

• Volume of the cylinder

Solution :

We know that,

★ Curved surface area = 2πrh

→ 220 = 2 × 22/7 × r × 14

→ 220 = 2 × 22 × r × 2

→ 220 = 88 r

→ r = 2.5

Now, to find the volume :

★ Volume = π r² h

→ Volume = 22/7 × 2.5 × 2.5 × 14

→ Volume = 1925/7

→ Volume = 275 cm³

$\therefore$ Volume of the cylinder is 275 cm³.

Answer 2

Step-by-step explanation:

Given Height=14 cm

CSA=220cm

CSA of cylinder=2*pi*r*h

2*22/7*r*14=220

2*22*r*2=220

88r=220

r=220/8

r=2.5cm

Volume of a cylinder=Pi*r^2*h

=22/7*2.5*2.5*14

=22*6.25*2

=275cm
