Four congruent circular holes with a diameter of 2 in. were punched out of a rectangular piece of paper. A rectangle with length 11 inches and width 8.5 inches. 4 circular holes with a diameter of 2 inches are cut out of the rectangle. What is the area of the paper that is left? Use 3.14 for Pi.
Answers
The area of the paper that is left is 80.94 square inches
Step-by-step explanation:
Length of rectangle = 11 inches
Width of the rectangle = 8.5 inches
Area of the rectangle = 11 × 8.5 = 93.5 inches²
Diameter of a circular hole = 2 inch
Radius of circular hole r = 1 inch
Area of a circular hole cut = πr²
= 3.14 × 1 × 1
= 3.14 inches²
Area of four circular holes = 4 × 3.14 = 12.56 inches²
Area of the paper left
= Area of rectangle - Area of circular hole
= 93.5 - 12.56
= 80.94 inches²
Hope this answer is helpful.
