Question

the height of a right circular cylinder is 5 cm and the area of its base is 36π cm^2. find the curved surface area of tge cylinder

Answer 1

$\sf{\large{GIVEN:-}}$

height (h) = 5cm
area of its base (πr²) = 36π cm²
Where, r is the radius of it's base.

πr² = 36π

r² = 36

r = 6cm

Now,we have r = 6cm ,h = 5cm.

and C.s.a of cylinder = 2πrh

2πrh = 2 * π * 6 * 5

= 60π cm²

Hence, the curved surface area of the cylinder = 60π cm²

Answer 2

Step-by-step explanation:

area of base(circular) = πr^2

36π = πr^2

r^2 = 36cm^2

r = 6cm

CSA of Cylinder = 2πrh

= 2*π*6*5

= 60π cm^2
