Question

A rectangular piece of paper 44cm x 40 cm is folded without overlapping to make a cylinder of height 4 cm. Find the volume of the cylinder.

Answer 1

Answer:

Step-by-step explanation:

By equating both areas l×b=2×pi×r(r+h)

From given 44×40=2×3.14×r(r+4)

44×40/2×3.14=r(r+4)

2765.71=r^2+4r

r^2+4r-2765.71=0

R=109.2

Therefore volume =3.14×(109.2)^2×4

14977.33
