Question

The height of the cylinder is 15 cm,whose curved surface area is 660 cm^2.Find the volume of the cylinder​

Answer 1

Answer:

Step-by-step explanation:

given

Height of cylinder =15cm

Curved surface area =660cm  

2

 

We know

Curved surface area =2πrh

∴2πrh=660

⇒r=  

2×π×15

660

​  

 cm=7.00 cm Ans.

Answer 2

Answer:

2310 is the answer.

Step-by-step explanation:

As we know,

$2\pi \: rh$

,

$\pi = 22 \div 7$

2*22/7*r*15

r=7

$v = \pi \: r ^{2} h$

22/7*7*15

Therefore it is 2310cm3
