Question

If the lateral surface of a cylinder is 94.2 cm and its height is 5 cm, then (i) radius of its base (ii) its volume. (Use A = 3.14)​

Answer 1

$\huge\red{Answer}$

(i) Let the radius of the base of the cylinder be r cm. Hence, the radius of the base is 3 cm. = 3.14 x (3)2 x 5 = 141.3 cm3.

ii) r = 3 cm h = 5cm

Volume of cylinder = πr²h

After solving the answer is 141.3 cm³

Answer 2

Step-by-step explanation:

$\huge\fbox{Solution}$

(i) Let the radius of the base of the cylinder be r cm. Hence, the radius of the base is 3 cm. = 3.14 x (3)2 x 5 = 141.3 cm3.

ii) r = 3 cm h = 5cm

Volume of cylinder = πr²h

After solving the answer is 141.3 cm³
