Radius of circle is the square root of 616/pi = 14m to nearest whole number
Diameter of circle is 2 times 14 = 28m
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
Use the formula for the circle: area = pi x radius squared. Replace the area, and solve for the radius. Multiply the radius by 2 to get the diameter.
The circumference of a circle is 2*pi*radius or diameter*pi
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
That depends on what information is given.Area of a circle: A = pi x radius squaredSolving for radius: radius = root(A/pi)Diameter of a circle = 2 x radiusSolving for radius:radius = diameter / 2Circumference of a circle: circumference = 2 x pi x radiusSolving for radius:radius = circumference / (2 x pi)
The diameter is twice the radius.
Use the formula for the area of a circle (A = pi x radius2). Replace the data you know (the area), and solve for radius. Then, you can double this radius to get the diameter.
That depends on the questions which have not been given but in general circular measurements are:- Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. We can solve for the radius by rearranging the formula: r = √(A/π) Given that the area is 78.5cm^2, we can substitute this value into the formula: r = √(78.5/π) ≈ 5.01cm Finally, we can calculate the diameter by doubling the radius: d = 2r ≈ 10.02cm Therefore, the diameter of the circle with an area of 78.5cm^2 is approximately 10.02cm.
Area of a circle = (pi) (radius)2 Radius = 1/2 (diameter) = 12. Area = (pi) (12)2 = 144 pi = 452.389 square units (rounded)
It depends on the information you have. If you remember the formulas for area and circumference, you can plug in what information you know in order to solve for the information you don't. You can multiply the radius by 2. If you are given the area, divide by pi (3.14) and then take the square root and multiply by 2. If you are given the circumference, divide by pi (3.14). The DIAMETER of a circle is any point on the circle to another point, straight across. The RADIUS of a circle is like the diameter, only from any point, to the very middle. To find AREA: multiply circumference by pi. To find Diameter, multiply the radius by two. to find radius: divide diameter by 2.
The formula for the circumference of a circle is 2*pi*radius or pi*diameter. In this case, it's 128=pi*d. Solve for d, and you get 40.74 feet.
