half the diameter times 3.141592654 squared
1319.47 meters squared
Divide the circumference by Pi (about 3.1416). The result is the diameter:255 / 3.1416 = about 81.17 meters diameter.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Area = 0.25*π*diameter2 or π*radius2 Diameter = 23 units gives an area of 415.48 square units
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Circumference : 94.2 meters Area : 706.5 square meters
225pi sq m
Area = pi * radius squared A = pi*r2 diameter/2 = radius 60 meters/2 = 30 meters so, Area = pi(30 m)2 = 2827 meters squared =================
The area of a pizza depends on the size of said pizza. If there is a certain pizza you would like to find the area of, all you need to do is: 1. measure the diameter of the pizza 2. split the diameter in half to get the radius 3. square the radius and multiply it by pi(3.14). For example, if I have a pizza with a diameter of 10 inches I would split that in half to get a radius of 5 inches. Then I would do this: (3.14) x 52. Which would end up being 78.5 in2. Tada, now you know how to get the formula of a pizza!

Area = (pi*92)/2 127.2345025 square meters
Radius: square root of (50/pi) = 3.989422804 Diameter: 2*3.989422804 = 7.978845608 or as 8 meters to nearest integer

TAKE hanf of 3.25 then square it An you will get 3.0625pie as your exact answer.
47 pee pee meters. (different person) By inches you should mean square inches because you're talking about area. Now to find the area of a circle, you have to find out the radius of the circle. The radius is half of the diameter, and the diameter is a line that goes half way through the circle. So when you find the radius, multiply it by itself, then multiply it by pi (3.14). If you didn't learn about all of this yet, than there's no other way I could help.
Divide the circumference by Pi (about 3.1416). The result is the diameter:255 / 3.1416 = about 81.17 meters diameter.
Assuming the pizza is round, use the same formula as area for a circle: A = Pi x R² where Pi = 3.1416 and R² is the radius multiplied by itself (the radius is one-half of the diameter). Using the formula: A = 3.1416 x (6.5 x 6.5) = 3.1416 x 42.25 = 132.7326 sq in.
