Answer to Problem 54STP
The circular shape pool is the greatest area as its radius is 9 ft.
Explanation of Solution
Given:
Three figures with dimensions:
Concept Used:
First figure is a rectangle. Area of rectangle is base times height
Area of rectangle:
Second figure is a composite figure. A right angle with two half
A = Area of rectangle + area of 2 half circle = Area of a rectangle + one full circle.
Total area of second figure:
Third figure is a circle. Area:
Calculation:
Let us calculate each area separately:
Area of rectangle: |
Rectangle: base = 10 ft and height = 12 ft. Circle : radius = 6 ft |
Area of circle: |
The circular shape pool is the greatest area as its radius is 9 ft.
Thus, the circular shape pool is the greatest area as its radius is 9 ft.
