Question

area of cylinder whose height is 28 and radius of base is 5 meter​

Answer 1

SOLUTION:-

Given:

•Height of the cylinder is 28m.

•Radius of the cylinder is 5m.

To find:

The total surface area of the cylinder.

Explanation:

Formula of the surface area of the cylinder;

=) 2πrh + 2πr²

Now,

$= > 2 \times \frac{22}{7} \times 5 \times 28 + 2 \times \frac{22}{7} \times 5 \times 5 \\ \\ = > \frac{44}{7} \times 5 \times 28 + \frac{44}{7} \times 25 \\ \\ = > 44 \times 5 \times 4 + \frac{1100}{7} \\ \\ = > 880 + \frac{1100}{7} \\ \\ = > (880 + 157.14) {m}^{2} \\ \\ = > 1037.14 {cm}^{2}$

Thank you.
