Question

Find the curved surface area of a cylinder whose radius is 7 cm and hiegh is 15 cm​

Answer 1

Answer:

Formula for curved surface area of cylinder = 2*pi*r*h

=> 2*(22/7)*7*15

=> 2*22*15

=> 660 cm^2

Answer 2

Step-by-step explanation:

Let's do this one!

you must remember the formula and everything will be easy afterwards...

Here,

Given,

Radius (R)=7cm

height (h)=15cm

CSA =?

As we know,

CSA of cylinder = 2πRh

= 2×π×7×15

= 659.4 cm² or 660 cm²
