Question

find the CSA of a cylinder if the circumference of the base is 22m and height is 5m​

Answer 1

Step-by-step explanation:

C= 22

2pie r = 22

2 × 22/7 ×r = 22

r= 22×7/ 22×2

r= 7/2 m

CSA of cylinder = 2 pie r h

2 × 22/7 × 7/2 ×5

= 22 × 5

110 m square

Answer 2

Answer:

Step-by-step explanation:

C= 22

2pie r = 22

2 × 22/7 ×r = 22

r= 22×7/ 22×2

r= 7/2 m

CSA of cylinder = 2 pie r h

2 × 22/7 × 7/2 ×5

= 22 × 5

110 m square
