What you do is, diameter divided by two, then multiply the diamter already divided in half multiplying by itself, then you would times the squared radius by pie(3.14) Example; diameter is 6 divided in half equals 2 because 6 divided by 3 equals two then spuare it which will be 4, then times it by pie or 3.14 :):):):):):):):):):):):):):):):)
By dividing its diameter by 2 is equal to the radius of a circle and its area is pi*radius2
find the radius of a circle with circumference of 42.1
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
You already know the radius.

Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
It is twice the radius of a circle
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by pi.
diameter is 2 times the radius 24
For a circle, circumference = 2 x pi x radius.
