Question

the curved surface area of a right circular cylinder of height 14 cm is 88cm². find it's volume.​

Answer 1

Answer:

2cm

Step-by-step explanation:

Let the radius and height of the cylinder be 'r' and 'h' respectively.

Curved Surface Area of a right circular cylinder = 2 π r h

Diameter = 2 × radius

Height of the cylinder, h = 14 cm

CSA of the cylinder = 88 cm²

2 π r h = 88 cm²

2 × 22/7 × r × 14 cm = 88 cm²

r = (88 cm² × 7) / (2 × 22 × 14) cm

= 1 cm

Diameter = 2 × radius

= 2 × 1 cm

= 2 cm

Answer 2

Thanks for your question...

Your required answer :

Given :

• Curved Surface Area = 88 cm²
• Height = 14 cm
• Radius = ?
• Volume = ?

Firstly we have to find its radius So :

• C S A = 2πrh

• 88 = 2πrh
• $88 = 2 \times \frac{22}{7} \times r \times 14 \\ \\ 88 = 2 \times 22 \times 2 \times r \\ \\ 88 = 88r \\ \\ r = \frac{88}{88} \\ \\ r = 1cm$

Therefore Radius = 1 cm

Now volume :

• 2 πr ( r + h )
• $2 \times \frac{22}{7} \times 1(1 + 14) \\ \\ \frac{44}{7} \times 15 \\ \\ = 94.2857 \: cm {}^{3}$
