The diameter of a circle is 13 m. Find its area to the nearest tenth.
To find the area of a circle, we can use the formula A = πr^2, where A is the area and r is the radius of the circle.
Since the diameter of the circle is 13 m, the radius is half of the diameter, which is 13/2 = 6.5 m.
Now, we can plug in the radius into the formula to find the area:
A = π(6.5)^2
A = π(42.25)
A ≈ 132.7 m^2
Therefore, the area of the circle is approximately 132.7 square meters.
