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 half the circle's diameter
the radius of a circle is r
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 the circle.
The radius of a circle is half the circle's diameter
the radius of a circle is r
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 radius of a circle is halve the circle's diameter.
