Question

the curved surface area of the cylinder is 4400 cm sq and the circumference of its base is 110cm. find the height and volume of the cylinder​

Answer 1

Answer:

4.57cm

Step-by-step explanation:

Circumference=110cm

2pi.r=110

pi.r=55

r=55×7/22

r=35/2

now,CSA of cylinder=4400cm^2

pi.r^2.h=4400

22/7×35/2×35/2×h=4400

h=4400×7×2×2/22×35×35

h=8×2×2/7

h=32/7cm

Answer 2

Answer:

Step-by-step explanation:

C.S.A.=2pi*r*h= 110h

h=4400/110=40cm

2pi*rh=4400

(40*44*r)=4400*7

r=(4400*7)/(40*44)

=17.5cm

volume= pi*r^2*h=(22/7)*17.5*17.5*40

= 38500 cm^3
