Answer:
Step-by-step explanation:
2πrh=4400
As 2πr=circumference of circle =220c.m
Therefore,
220*h=4400
H=20 cm

Answer:
csa of cylinder = 4400cm2
r = 220/2
r= 110
csa of cylinder = 2 x 22/7 x 110 x h = 4400
= 44/7 x 110h = 4400
= 4840/7h = 4400
= 4840h = 4400 x 7
h = 30800/ 4840
h = 7 cm
hope this helps :)

It's wrong
varsha ur ans is right but i cant understand step can u pls tell it step by step plss..
Yaa sure
Firstly you know the curved surface area of cylinder which is 4400square cm
Now you have to substitute the value of circumference of circle which is equal to 2πr which is given in your question the value is 220cm. Now just put this value in the 2πrh and you'll get the h value
what is the value of r
