Question

Find the area of curved surface if area of base of cylindrical tank is 176 cm square and height is 30 cm

Answer 1

Answer:. 5280 cm^2

Step-by-step explanation: Given circumference of base = 176 cm

Which means 2π r = 176 cm

Height = 30 cm

CSA of a cylinder = 2πrh

= Circumference* h

= 176 × 30

= 5280 cm^2

Answer 2

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.

$A=\pi r^2$

$176=\pi r^2$

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

$r^2=56$

$r=\sqrt{56}$

$r=7.48\ cm$

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.
