Question

The curved surface area of a cylinder is 176cm2 and its base area is 38.5 cm2,find the volume of cylinder .[use pie 22/7]

Answer 1

C.S.A = 2πrh
volume = πr²h
area of base = πr²
38.5 = 22/7*r²
r² = 12.25
r = 3.5 cm
C.S.A , 
176 = 2 * 22/7 * 3.5 *h
176 = 22h
176 / 22 = h
h = 8 cm
volume = πr²h
= 22/7 * 3.5*3.5 * 8
= 308 cm³
