Circumference = 2*pi*5.2 meters
The circumference of a circle if the diameter is 52 is 163.4 units.
circumference of the circle = pi*52 cm
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
The formula for the area of a circle is A = pi x r2 where r is the radius. If the diameter of the circle is 10 meters, then the radius is half that amount or 5 meters. Plug that value into the formula for r, using 3.14 as an approximation for pi. The area is 3.14 x 52 or about 78.5.
circumference or perimeter of the semi-circle = (diameter*pi)/2 + diameter
Oh, dude, so the diameter of a circle is just the distance across the circle passing through the center, right? Well, to find the diameter when you know the circumference, you divide the circumference by π (pi), which is like 3.14 or something. So, for a circle with a circumference of 52 inches, the diameter would be 52 divided by π, which is about 16.5 inches. Easy peasy!
The circumference of a circle, C, is pi*diameter. If 52 is the diameter, then the equation becomes: C = 3.14159 * 52 or C = 163.36 inches.
Radius = 4.068 miles (to 3 dp)
13 m
the formula for the area of a circle is pi r2 (pie are square). r is the radius. examples: radius of circle is 5. pi 52 = pi 25 = 78.53
A = Pi*r2 = Pi*52 ≈78.54
Remember the circle eq'n C = pi*d Algebraically rearranging d = C / pi Hence d = 52 pi / pi Cancel down by 'pi' Hence d = 52.
