A cylindrical solid is 40 cm high and has diameter of 2 cm. What is it

1.	A cylindrical solid is 40 cm high and has diameter of 2 cm. What is its volume in cm*?a) 100b) 120c) 140d) 160e) 180
Answer» The dimensions of the cylinder is : height of the cylinder = h= 40 inches diameter = d = 2 inches radius = d/2 r = 2/2 = 1 inch volume of the cylindrical solid =πr²h cubic units V = 22/7× 1²× 40 V = 880 / 7 V = 125.714 cubic inhes

Answer»

The dimensions of the cylinder is :

height of the cylinder = h= 40 inches

diameter = d = 2 inches

radius = d/2

r = 2/2 = 1 inch

volume of the cylindrical solid =πr²h cubic units

V = 22/7× 1²× 40

V = 880 / 7

V = 125.714 cubic inhes
