______ .
(a) 2πr
2
(b) 3πr
2
(c) 4πr

2 (d) πr
2

Answer 1

Answer:

The radius 'r' of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.

Answer 2

Answer:

the radius of the a angle
