A window is in the shape of a circle with a radius of 1.5 feet. What is the area to the nearest tenth of a square foot? (Use straight pi equals 3.14.)
1.8
4.7
7.1
9.4
The area of a circle is calculated using the formula A = πr^2, where π is approximately 3.14 and r is the radius.
Given that the radius of the circle window is 1.5 feet, we can substitute this value into the formula:
A = 3.14 * (1.5)^2
A = 3.14 * 2.25
A = 7.065
Therefore, the area of the window is approximately 7.1 square feet (7.1).
