Question

The curved surface area of a cylinder is 242πcm^2.If the base radius and the height of the cylinder are the same,find the height of the cylinder.

Answer 1

Answer:

Step-by-step explanation:

csa=2πrh

242πcm^2=2πr^2(since r=h)

242π/2π=r^2

121cm^2=r^2

r=h=11cm

Answer 2

Answer:

height = 11 cm.

Step-by-step explanation:

CSA of cylinder = 242 πcm², r = h, h = ?

2πrh = 242 π cm.

2rh = 242.

rh = 121.

h×h = 121. (r = h)

h² = 121.

h = 11 cm.

. ' . Height of the cylinder is 11cm.....
