Question

33 cm long and 15 cm wide rectangular paper is rolled along its length to get a cylinder of height 15 cm find the volume of the cylinder


please tell me answer ​

Answer 1

length of rectangle=33cm

breadth of rectangle=15cm

now, after folding

height=15cm

circumference of base=2πr

33=2*22/7*r

r=33*7/22/2

r=21/4

we know that

volume=πr²h

22/7*21/4*21/4*15

10395/2cm³
