Well, darling, the area of a circle is calculated using the formula A = πr², where r is the radius. So, if the radius is 42 mm, plug that bad boy in and you'll get an area of approximately 5,539.82 square millimeters. Just remember, math doesn't care about your feelings, it's all about those numbers.

The area of a circle is calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. If the circle has a diameter of 42 mm, the radius would be half of that, which is 21 mm. Plugging this value into the formula, we get A = 3.14159 x (21 mm)^2 ≈ 1385.44 mm^2. Therefore, the area of a circle with a diameter of 42 mm is approximately 1385.44 square millimeters.
A circle with a diameter of 25 mm has an area of 490.9 square mm.
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
Area = pi*552 square mm
Area = pi*282 square mm
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
