Question

The volume of a cylinder is $54\pi c{m}^3$ and height is 14 cm. Then its curved surface area is $168\pi c{m}^2$
If true then enter $1$ and if false then enter $0$

Answer 1

Volume of a Cylinder of Radius "R" and height "h" $=\pi R^{2}h$
Hence, volume of the given cylinder $=\pi \times R^2\times 14=54\pi {cm}^3$

$R^2=3.86$

$R=1.96$ cm

Curved Surface Area of a Cylinder of Radius "R" and height "h" $=2\pi Rh$

Hence, CSA of the given cylinder $=2\times \pi \times 1.96\times 14=54.88\pi sqcm$
