Question

The volume and area of curved surface of a right circular cylinder are 1540 m^3 and 440 m^2 respectively. Find the radius of the base and the height of the cylinder

Answer 1

your answer is here.

Answer 2

The radius of the base and the height of the cylinder are 7 m and 10 m respectively.

Step-by-step explanation:

Curved surface area of cylinder =$2 \pi r h$

We are given that curved surface area of cylinder is 440 sq.m.

So,$2 \pi r h =440\\\pi r h = 220$

Volume of cylinder = $\pi r^2 h =\pi r \times r \times h = 220r$

We are given that volume is 1540

So, 220r=1540

$r=\frac{1540}{220}$

r=7 m

$\pi r h = 220\\\frac{22}{7} \times 7 h = 220$

h = 10

Hence the radius of the base and the height of the cylinder are 7 m and 10 m respectively.
