i. Given: r = 4.2 cm and h = 5 cm
To find: Volume of the cylinder.
Volume of the cylinder = πr2h
=\(\cfrac{22}{7}\) x 4.2 x 4.2 x 5
= 22 x 0.6 x 4.2 x 5
= 277.2 cc
∴ The volume of the cylinder is 277.2 cc.
ii. Given: r = 5.6 cm and h = 5 cm
To find: Volume of the cylinder.
Volume of the cylinder = πr2h
= \(\cfrac{22}{7}\)x 5.6 x 5.6 X 5 7
= 22 x 0.8 x 5.6 x 5
= 492.8 cc
∴ The volume of the cylinder is 492.8 cc.
