Radius = about 13cm Diameter = about 26cm
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
A circle with a radius of 4.5Cm has an area of 63.62Cm2
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
Area of a Circle = (pi)(r^2) Diameter = 2r If the diameter of the circle is 12, then the radius has to be 6. If the area of a circle is pi times the square of the radius, and the square of 6 is 36 (6x6), then the area of the circle is 36pi.
No. The area of a circle is 3.142 x radius x radius (radius is half the diameter).
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
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)
By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
Radius = about 13cm Diameter = about 26cm
If area of circle is equaled to 100pi what is the radius?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
Yes because the area of a circle is pi*radius squared
diameter is 15 area of the circle is... 706.5 if im not mistaken
A circle with a radius of 4.5Cm has an area of 63.62Cm2
The area of any circle is (pi) x (radius)2 .The radius is 1/2 of the diameter.
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
