How do you find the radius of a circle math
WebArc length = rθ × π/180 × 180/π = rθ. Thus, the arc of a circle formula is θ times the radius of a circle, if the angle is in radians. The arc length formula can be expressed as: arc length, L = θ × r, when θ is in radian; arc length, L = θ × (π/180) × r, where θ is in degrees, where, L = Length of an Arc. θ = Central angle of Arc. WebMr. J will go through what the radius and diameter of a circle are and explain the steps of finding the radius given the diameter. More Circle Videos: Parts of a Circle Center, …
