Question

curved surface area of a cylinder is 1980cm and radius of its base is 15cm. find the height of the cylinder

​

Answer 1

Answer:

Height=21 cm

Step-by-step explanation:

CSA=2πrh

1980=2×22/7×15×h

1980×7/2×22×15=h

h=21cm

Answer 2

Answer:

Heyaa♡♡

Radius of base of cylinder (r) = 15 cm

Let the height = h cm

As we know :-

Curved Surface Area of Cylinder :-

$2\pi \: rh$

CSA = 1980 sq. cm (given)

$= > 2 \times \pi \: rh = 1980cm {}^{2} \\ = > 2 \times \frac{22}{7} \times 15 \times h = 1980 \\ = > h = \frac{1980 \times 7}{2 \times 15 \times 22} \\ = > h = 3 \times 7 \\ = > h = 21cm$

Therefore,

Height of the Cylinder is 21cm

Hope it helped you.
