WebApr 10, 2024 · In mathematics, Circle is a two-dimensional figure which is round in shape. All the points on the boundary of the circle are equidistant from a point inside the circle which is known as the center of the circle. The distance between the center of the circle to the point on its boundary is termed as the radius of the circle which is denoted as ... WebMay 21, 2024 · The radius formula derived from the area of a circle is written as: Radius = √ (Area/π) units. Example: If the diameter is given as 24 units, then the radius is 24/2 = 12 units. If the circumference of a circle is provided as 44 units, then its radius can be calculated as 44/2π. This implies, (44×7)/ (2×22) = 7 units.
