Question

the curved surface area of a right circular cylinder of height 14 cm is 88 cm^ .Find the diameter bof the base of cylinder​

Answer 1

Step-by-step explanation:

curved surface area=2πrh

88=2*22/7*r*14

1cm=r

diameter=2r

=2*1

=2cm

Answer 2

Let the radius of a cylinder be 'r'.

Given :- Height (h) of a cylinder = 14 cm

Curved surface area of a cylinder = 88 sq. cm

Curved Surface area of a cylinder = 2πrh sq. unit

According to the question,

$2\pi \: rh = 88$

$= > 2 \times \frac{22}{7} \times r \times 14 = 88 \: \: \: (taking \: \pi = \frac{22}{7} )$

$= > 2 \times 22 \times r \times 2 = 88$

$= > 88 \times r = 88$

$= > r = \frac{88}{88}$

$= > r = 1$

Radius of a cylinder = 1 cm.

therefore, Diameter = 2* r

= 2 * 1 cm.

= 2 cm.

Answer :- Diameter of the base of a cylinder is 2 cm.
