The floor of a room is a square with side of 16 feet. A circular rug is placed on the floor. The rug touched each of the four walls. How much of the floor is not covered by the rug?

Question

Put your answer in decimal form!

Answer 1

Find the area of the room and the area of the circle rug and then subtract those two answers.

Area of the room:

Area=side squared

A=16 x 16

A=256

Area of the circle rug:

Area=Pi times radius squared

A=3.14 x 8 squared

A=3.14 x 64

A=200.96

Area of the room minus area of the rug:

256-200.96=55.04
