Question

give me a full solution of question 11

Answer 1

Given,
Circumference=120cm
Curved surface area(CSA)=4800cm²
:.Height of the cylinder =CSA/Circumference
=4800/120
=40cm
Since Circumference=2πr=120
:.r=120/2π
R=60/22×7
R=30/11×7
Volume=πr²h
:. Putting value
22/7×30/11×7×30/11×7×40
=3054.545454545454......cm³
