3 inches, perhaps!
A circle with a radius of 3 inches has an area of 28.27 square inches.
Circumference: 2*pi*3 = 6*pi inches
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
the radius of a circle is r
The radius of a circle is half the circle's diameter
A circle with a radius of 3 inches has an area of 28.27 square inches.
A circle with a radius of 1.5 inches (d/2) has a circumference of 9.4 inches.
Circumference: 2*pi*3 = 6*pi inches
The volume of a cylinder with a 3in radius and 10in height is: 283 cubic inches.
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
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.

The radius of a circle = the diameter of the circle divided by 2
