Question

If the curved surface area of a cylinder is 94.2 cm^2 and height is 5cm, then find radius of its base and volume of the cylinder. (Use π =3.14)​

Answer 1

Answer:

r=3cm,volume=141.2cmcube3

Step-by-step explanation:

Answer

Given, h=5cm

⇒Let radius =r

(i) Curved Surface Area

⇒94.2cm 2

=2πrh

⇒94.2 cm 2

=2×3.14×r×5cm

⇒r=3cm

(ii) Volume of cylinder

⇒πr 2

h=3.14×3×3×5

=141.2cm 3
