Question

During the summer season some volunteers thought of providing wather to thirsty people.so they utilished some space along the main road and placed a cylindrical vessel of water. The circumeference of the base of cylindrical vessel is 132cm and its height is 25cm. How many liters of water can vessel hold.

Answer 1

Circumference of the circle
$2\pi r$
Therefore,
132=2*22/7 * r
132*7/22*2 = r
3*7 = r
21 cm = r
Volume of the cylinder
$\pi{r}^{2}h$
Therefore,
22/7 * 21*21*25
=22*3*21*25
=66*525
=34650 cm^3
