diameter is simply twice the radius.
50 centimeters
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
The diameter is 20. (The diameter is twice the radius. The radius is from the center to any edge of the circle.)The circumference is 62.83. ( The diameter X Pi (3.14... equals the circumference.)OR:Using only the radius: (2 X Pi X radius will also equal the circumference.)In this example 2 X 3.14 X 10 (2 X 3.14 = 6.28 X 10= 62.8)
Assuming you mean the circle has a 3.5 meter radius, the area of a circle is Pi * r2, so 3.14 * 3.5 * 3.5 = 38.465 m2.
The process you would use to find the circumference of a circle completely depends on what information you already have about the circle. For example, you might be given the circle's area, or its radius, or its diameter, or the length of one radian of arc along the circumference, and each of those would require a different method to find the circumference. The easiest example is the one where you know the circle's diameter. In that case, simply multiply the diameter by (pi) to get the circumference. The next easiest case is the one where you have the circle's radius ... let's say the radius is 1.5 meters. Knowing that the radius is half of the diameter, you first double the radius, and find that the diameter 3.0 meters. Then you get the circumference just as you did in the first example ... multiply the diameter by (pi). With a radius of 1.5 meter, you would find that the circumference is about 9.425 meters. (rounded)
If the diameter is 1 metre then the radius is 0.5 metre.
Diameter of the circle: 2 times 1 = 2 meters
50 centimeters
Radius: 160/2 = 80 cm
Circumference of a circle = 2*pi*radius or diameter*pi
First, divide the circumference by pi (about 3.1416). This gives you the circle's diameter. Then divide the diameter by two to get the radius:10.99m / 3.1416 = 3.5m diameter3.5m / 2 = 1.75 meter radius
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
Circumference of a circle = 2*pi*radius or pi*diameter
if a circle has an 18 meter diameter, then it has a 9 meter radius the circumference of a circle is 2(pi)r so the c. would be 2(pi)(9) which is 18pi. (another way to think of circumference is the diameter times pi)
The circumference of a circle (C) = 2 x pai x radius = pai x diameter Accordingly, the circumference = 3.14 x 1 meter = 3.14 meters
If by an 8 inch circle, you mean that the circumference is 8 inches, then the radius would be found using: C =pi x diameter 8 =3.14 x diameter 8/3.14= diameter and since diameter = 2 x radius 2.55 = 2 x radius 2.55/2 = radius therefore, the radius is approximately 1.27 inches
diameter= 5m radius= diameter/2 = 5/2 =2.5m area of the circle= πr*r =22/7*2.5*2.5 =19.64....m
