Question

The curved surface area of a right circular cylinder of height 14cm is 88cm find the diameter

​

Answer 1

The curved surface area of a right circular cylinder of height 14cm is 88cm

=2πrh=88

=2×22÷7×r×14=88

r = 1cm

Diameter = 2×Radius

               = 2×1

                = 2cm

Answer 2

$\huge{\boxed{\sf{\red{Required \: Answer:}}}}$

GiveN:

• Curved surface of the cylinder is 88 cm
• Height of the cylinder = 14 cm

To FinD:

• Diameter of the base?

Step-by-step Explanation:

Curved surface area of cylinder can be determined by:

$\large{ \boxed{ \rm{CSA = 2\pi rh}}}$

Here, r is the radius of the base and h is the height of the cylinder.

Now putting the values to get the radius first,

⇒ 2πrh = CSA

⇒ 2 × 22/7 × r × 14 cm = 88 cm²

⇒ 88r cm = 88 cm²

⇒ r = 1 cm

Then, Diameter of the cylinder:

= 2 × Radius

= 2 × 1 cm

= 2 cm

Hence,

The diameter of the base of the cylinder is 2 cm (Ans)
