Top / lid of cylinder

Based of cylinder

Right face/blanket /curved surface

Area of top+base =2πr2.

Curved surface = area of rectangle l = perimeter of circle Wide = height of cylinder

1. Given that :h = 15 cm, r = 7 cmFind :a. The area of curved surfaceb. The surface area of cylinder

a) . The area of the curved surfaceb) . The surface area of the cylinder

3. Find the height of cylinder if gifen that the area of the curved surface is 880 cm², the base diameter is 14 cm.

4. Find the heght of a cylinder whose base radius is 15 cm, surface area is 5, 181 cm².

a). The base radiusb). The height of the Cylinder

6. The area of the curved surface of a cylinder is 251.2 cm². If the ratio of the base radius to the height is 2 :5, find :a)Base radiusb)The height of cylinder.
