circumference of cylinder= 2(pi)rh=132 cm
2×22×r×22/7=132
44×22r/7=132
22r=3×7
r=21/22
volume of cylinder= (pi)r^2h= (22/7)×(21/22)^2×22= 22*22*21*21/7×22×22
= 21×3= 63cm^3
2×22×r×22/7=132
44×22r/7=132
22r=3×7
r=21/22
volume of cylinder= (pi)r^2h= (22/7)×(21/22)^2×22= 22*22*21*21/7×22×22
= 21×3= 63cm^3
