A circle is a curve sketched out by a point moving in a plane. The radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that diameter of the circle is 26 inches. Therefore, the radius and the circumference of the circle can be written as,
Diameter of circle = 2 × (Radius of the circle)
Radius of the circle= Diameter of circle / 2
Radius of the circle = 26 inches / 2
Radius of the circle = 13 inches
Circumference of circle = 2 × π × (Radius of the circle)
= 2 × π × 13 inches
= 26π inches
= 81.6814 inches
Hence, the radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
