To find the diameter of the base of the cylinder, we need to use the formula for the curved surface area of a cylinder, which is given by:

Curved Surface Area = 2Ï€rh

where r is the radius of the base and h is the height of the cylinder.

In this case, the curved surface area is given as 88 sq. cm, and the height is 14 cm. We can rearrange the formula to solve for the radius:

Curved Surface Area = 2Ï€rh
88 = 2Ï€r(14)
88 = 28Ï€r

Dividing both sides of the equation by 28Ï€ gives:

88 / (28Ï€) = r

Now we can calculate the radius:

r â‰ˆ 0.314 cm

Finally, to find the diameter, we can multiply the radius by 2:

Diameter = 2r â‰ˆ 2 * 0.314 cm

Diameter â‰ˆ 0.628 cm

Therefore, the diameter of the base of the cylinder is approximately 0.628 cm.
