radius = 20/2*pi = 3.183098862 m
Area = pi*202 = 1256.637 square m to 3 dp
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
the circumfrence of a circle is pi times it's radius squared.
125.66m
Area = pi*202 = 1256.637 square m to 3 dp
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
correct bend on the circle
the cylinder is approximately 50240 m3 the sphere is approximately 33493 and 1/3 m3
the radius of a circle is r
The radius of a circle is half the circle's diameter
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.

It is the radius of the circle.
