Question

11.
The volume (in cu. cm.) of a right circular
cylinder with radius 1 cm and height 2 cm is:
1 सेमी त्रिज्या तथा 2 सेमी ऊचाई के लम्बवृत्तीय
बेलन का आयतन (घन सेमी में) है।
Talke n = 22
(b) 22
(a) 22
(c) 44
​

Answer 1

Radius = 1

Hieght=2

Volume of cylinder is pi * r^2

Pi is 22/7 as given

22/7*2*1*1 which is 44/7

But pinis given as 22 so volume is 44
