The volume of a room is 400 cu. m and its height is 25 m. find the cost of carpeting the floor of the room at 5 paisa per sq. cm.

Step-by-step explanation:

This only works if the room is a prism shaped, or cylinder.  

Volume of a prism or cylinder is area of he base times height.  So since we know the height and volume we can fand the area.

V = h*B

B = V/h

B = 400/25

B = 8

This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
