In a circle of radius 14 cm

WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. WebR = radius of circle (known) x = length of equilateral triangle Draw the figure (outside equilateral triangle with inscribed circle). Put a dot in the center of the circle. Draw a line from the center of the circle to a point where the circle barely touches the triangle. This forms a right angle with that line, and that length = R (radius).
