The diameter of a circle is 13 in. Find its area to the nearest whole number

Answer 1

To find the area of a circle, you can use the formula:

Area = πr^2

Given that the diameter of the circle is 13 inches, we can find the radius by dividing the diameter by 2:

Radius = 13 / 2 = 6.5 in

Now plug this radius value into the formula to find the area:

Area = π(6.5)^2
Area = π(42.25)
Area ≈ 132.73 in^2

Rounded to the nearest whole number, the area of the circle is 133 in^2.
