Question

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

Answer 1

heyy.. frnd here is ur answer

CSA=88cm^2

2πrh=88cm^2

2×22/7×r×14=88cm^2

44×2×r=88cm^2

88×r=88cm^2

r=88/88

r=1cm

therefore diameter is 1×2=2cm

hope this helps

Answer 2

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)
