Question

The curved surface area of a right circular cylinder is 4224 cm. If its height is 33 cm, find its volume.

Answer 1

Answer:

43025 cm^3

Step-by-step explanation:

Atq, 2πrh=4224

or r= 4224/2π×33

or, r= 20.37 cm

now, volume = πr^2 h

= π× (20.37)^2 × 33

= 43025. 31 cm^3

Answer 2

Answer:it's volume is 172

032 sq cm

Step-by-step explanation:

Given, height = h = 33 cm

Let, radius = r cm

According to the the question,

2πrh = 4224

, 2×(22/7)× r ×33 = 4224

, r = (4224×7)/(2×22×33) = 224/11 m

It's volume = 4πr^2h

= 4×(22/7)×(224/11)^2× 33

= 172032 sq cm
