WebJan 24, 2024 · Ans: The radius of a circle is the distance from the centre of the circle to any point on its circumference. A diameter of a circle is twice the length of a radius in a circle. It is the largest chord of a circle that passes through the centre of the circle. It is a line segment that bisects the circle. WebMar 29, 2024 · Explanation: The diameter of a circle is two times the radius, or, d = 2r. This means that the radius is one half of the diameter, r = 1 2 d. So, if d = 12 cm, r = 1 2(12) …
Circles: Radius, Diameter, and Circumference Jeopardy Template
WebThe equation for diameter of a circle from circumference is: d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area is the space contained within the circle's boundaries. WebFeb 2, 2024 · The radius of a circle from the area: if you know the area A, the radius is r = √(A / π).
