Find the area of the circle with the given radius or diameter. Use "3.14" for π. Round your answer to the nearest tenth. Diameter =42.0 137.6mm 2 376.7 mm2 376.7 mm² 1,384.7 mm² 6,027.0 mm2

The area of a circle can be found using the formula: A = π * r^2, where r is the radius of the circle.

Given the diameter, we can find the radius by dividing it by 2. So, the radius (r) of the circle is 42.0 / 2 = 21.0.

Plugging the value of the radius into the formula, we get: A = 3.14 * (21.0)^2 = 3.14 * 441.0 ≈ 1384.7 mm².

Therefore, the area of the circle is approximately 1384.7 mm².
