Question

find the volume of cylinder if the circumference of the cylinder is 132 cm and height is 25 centimetre​

Answer 1

Answer:

2Πr =132

r=132×7÷22 ×2

r=21cm

h= 25cm

volume= Πr×rh

v= 22/7×21×21×25

v=22×3×21×25

v= 34650 cm×cm×cm

Answer 2

Answer:

The volume of cylinder is 34651.4 cm³

Step-by-step explanation:

Given as :

Circumference of cylinder = 132 cm

The height of cylinder = h = 25 cm

Let The volume of cylinder = v cm³

According to question

Circumference of base of cylinder = 132 cm

i.e 2 π × r = 132 cm

Or, 2 × 3.14 × r = 132 cm

or, 6.28 × r = 132 cm

∴    r = $\dfrac{132}{6.28}$

i.e  r = 21.01 cm

So, radius = r = 21.01 cm

Since , volume of cylinder = v = π × r² × h

Or, v = 3.14 × (21.01)² × 25

∴  v = 34651.4 cm³

So, The volume of cylinder = v = 34651.4 cm³

Hence, The volume of cylinder is 34651.4 cm³  Answer
