WebFeb 28, 2024 · Using the radius of the circle equation ( x − h) 2 + ( y − k) 2 = r 2. Substituting the value in the equation we get: ( 7 − 3) 2 + ( 6 − 3) 2 = r 2 4 2 + 3 2 = r 2 16 + 9 = r 2 r 2 = 25 r = 5 Thus, the radius of the circle with the equation ( … WebThe formula of radius of a circle is often denoted by “r”. There are different formulas for different events, much like: Radius = C/2π (for circumference), Radius = √ (A/π) (for area), Radius = D/2 (for diameter). Most circle related formulas, like circumference and area, are determined by first considering the radius. Also read: Area of a Triangle
