To find the area of a circle, you can use the formula A = ฯr^2, where A is the area and r is the radius of the circle.
In this case, we are given the diameter of the circle, which is 8 inches. The radius is half the diameter, so we can calculate it by dividing the diameter by 2:
r = 8 inches / 2 = 4 inches
Now we can substitute the value of the radius into the formula to find the area:
A = 3.14 * (4 inches)^2 = 3.14 * 16 square inches โ 50.24 square inches
To the nearest tenth, the area of the circle is approximately 50.2 square inches.
So, the correct answer is B. 50.2 in^2.
3.14 * 4^2
Formula: 3.14*R^2
R=8/2 R=4
Answer B
