Answer 1

Hi mate

The area of curved surface is 1410.51 square cm

.

Step-by-step explanation:

Given : Area of base of cylindrical tank is 176 cm square and height is 30 cm ?

To find : The area of curved surface ?

Solution :

Area of base of cylindrical tank is 176 cm square.

$a = \pi {r}^{2}$

$176 = \pi {r}^{2}$

${r}^{2} = \frac{176}{ \frac{22}{7} }$

${r}^{2} = 56$

$r = \sqrt{56}$

$r = 7.48cm$

The height is h=30 cm.

The curved surface area of the cylindrical tank is

$csa = 2\pi rh$

$csa = 2 \times \frac{22}{7} \times 7.48 \times 30$

$csa = 1410.51 {cm}^{2}$

Therefore, the area of curved surface is 1410.51 square cm.
