Answer 2

Given -

• Circumference = 88 cm$.$
• Height of cylinder = 30 cm

To Calculate :-

• Find volume ?

SoLuTioN :-

So , let's find out radius

We know that :-

• Circumference = 2πr

From given ,

↠ 88 = 2 × 22/7 × r

↠ 88 = 44/7 × r

↠ 88 × 7 ÷ 4 = r

↠ r = 14 cm

↠ radius = 14 cm

Therefore ,

➤ Volume of a cylinder = πr²h

Now, putting the values in the above formula , we get

↠ Volume = 22/7 × (14)² × 30

↠ 22/7 ×196 × 30

↠ 129360 ÷ 7

= 18480 cm³

Hence , volume of a cylinder is 18480 cm³.
