How do you find out the radius of a circle
WebJul 26, 2024 · Parts of a Circle. In day-to-day life, many circular shapes are seen and used, for example, wheels, cups and saucers, cricket grounds, etc. In any circle, the center point is the midpoint of a ... WebRadius: the distance between any point on the circle and the center of the circle. It is equal to half the length of the diameter. Diameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle. It is equal to twice the length of the radius.

WebDec 16, 2024 · For example, to know how to find the square feet of a circle with a 1524 cm radius, follow these steps: Convert 1524 cm to ft by dividing it by 30.48. The radius in cm would be: (1524/30.48) ft = 50 ft. Learn more about this in our length converter. Input the radius in the SF formula: SF = π (50 ft)² = 7854 ft².
WebThe center is at the origin. The equation of a circle in standard form is: (x−h)²+ (y−k)²=r². Where r is the radius and (h,k) is center. If either -h or -k is missing, then its value must be 0. Thus, if both are missing the circle must be centered at the origin, (0,0).
