Question

the curved surface area of cylinder is 1100 cm square and circumference of its base 220 cm find radius and height??​

Answer 1

Answer:

Circumfernce of cirlce = 220 cm ( given )

=>2πr = 220

=> 2x 22/7x r = 220

=> r= 220 x7 / 2 x 22

=> r = 35 cm

C.S .A of cylinder = 1100 cm ( given )

=> 2πrh= 1100

=> 2x 22/7 x35x h = 1100

=>h = 1100x 7/2x22x35

=>h = 5 cm .
