 \pi r² = 110
r² = 110×7/22
≈6
2 \pi rh = 4400
2×22/7×6×h=4400
h = 100×7/6
   =700/6
   =116.7
V =  \pi r²h
   =22/7×6²×116.7
   =13203.77

Circumference of its base = 2 \pi r
110/2 = 22/7*r
55 = 22/7*r
55*7/22 = r
35/2 = r
Curved surface area of the cylinder = 2 \pi rh
4400 = 2*22/7*35/2*h
4400 = 22*5
4400/110 = h
4 = height
Volume of a cylinder =  \pi  r^{2} h
Volume of the cylinder = 22/7*4*35/2*35/2
Volume of the cylinder = 3850
