Circumference of Circle =2×π×r where, r is the radius. Curved Surface Area of Cylinder =2πrh Volume of Cylinder =πr2h where r is the radius and h is the height of Cylinder. Explanation: Curved surface area =4400cm2 Circumference of the base =110cm π=22∕7 Circumference =2πr 110=2×(22∕7)×r r=110×7∕(2×22)=17.5cm Now, Curved surface area =2πrh 4400=2×(22∕7)×17.5×h h=4400×7∕(2×22×17.5)=40cm Volume =πr2h Volume =(22∕7)×(17.5)2×40 Volume =38500cm3 Volume =0.0385m3 Therefore, the volume of the right circular cylinder is 0.0385m3.
