if it's a circle it's: 706.9=pi(r2) which makes the diameter about 30.0009 cm
A circle with a diameter of 25 mm has an area of 490.9 square mm.
It works out as slightly over 30 mm
The area of a 10p (10 pence) coin is approximately 2.3 square centimeters. It has a diameter of 24.5 millimeters and a thickness of 1.7 millimeters. To calculate the area, you can use the formula for the area of a circle (A = πr²), with the radius being half the diameter.
A 12 mm circle has a diameter of 12 millimeters, which is slightly less than half an inch (approximately 0.47 inches). The radius, which is half the diameter, is 6 mm. In terms of area, the circle has an area of about 113.1 square millimeters. This size is comparable to the diameter of a large button or a small coin.
5000.Area of a square = 0.5*(diameter)^2
A circle with a diameter of 25 mm has an area of 490.9 square mm.
Using 3.14 as Pi the area of circle is: 961.625
It works out as slightly over 30 mm
The area of a 10p (10 pence) coin is approximately 2.3 square centimeters. It has a diameter of 24.5 millimeters and a thickness of 1.7 millimeters. To calculate the area, you can use the formula for the area of a circle (A = πr²), with the radius being half the diameter.
Area = pi*182 = 1017.876 square mm to 3 decimal places
Well, honey, if the diameter of a circle is 7 mm, then the radius is half of that, which is 3.5 mm. The formula for the area of a circle is πr^2, so plug in 3.5 for the radius and you get an area of approximately 38.48 square millimeters. So there you have it, darling!
A 12 mm circle has a diameter of 12 millimeters, which is slightly less than half an inch (approximately 0.47 inches). The radius, which is half the diameter, is 6 mm. In terms of area, the circle has an area of about 113.1 square millimeters. This size is comparable to the diameter of a large button or a small coin.
If the area is 81 millimeters, the side length is the square root of that, or 9 millimeters.
The area of a square with sides of length 7 mm: 7 millimeters times 7 millimeters are 49 square millimeters.
5000.Area of a square = 0.5*(diameter)^2
A 20mm circle has a diameter of 20 millimeters, which is equivalent to 2 centimeters or approximately 0.79 inches. The radius of the circle is half of the diameter, so it measures 10mm. This size is comparable to a small coin, such as a dime. In terms of area, the circle has an approximate area of 314 square millimeters.
The area of square is : 2304.0
