Question

find CSA and TSA of cylinder whose radius is 14 and height is 8 ​.​

Answer 1

Solution :

2 × 22/7 × 14 (14 + 8)

= 2 × 22/7 × 14 × 22

= 1936 square cm

Answer 2

Answer:

• 704 cm²
• 1936 cm²

Step-by-step explanation:

Given

• Radius = 14 cm
• Height = 8 cm

To find

• C.S.A of cylinder
• T.S.A of cylinder

Solution

Curved surface area :

↪ 2πrh

• 2 × 22/7 × 14 × 8
• 44/7 × 112
• 704

∴ C.S.A is 704 cm²

Total surface area :

↪ 2πr(r + h)

• 2 × 22/7 × 14(14 + 8)
• 44/7 × 14(22)
• 88 × 22
• 1936

∴ T.S.A is 1936 cm²
