WebApr 29, 2011 · What is the radius of a circle in millimeters? It varies on how large the diameter and radius is. True, but with the radius you know to double it and you have the diameter. If you muliply Pi (3.14....) times the diameter, you get the circumference. So radius = circumference divided by Pi, with that answer (which is "diameter")then divided by two. WebMar 12, 2024 · This indicates that the radius is equal to the diameter divided by two. \( Diameter = 2\times Radius \) \( r = \frac{d}{2} \) \( r = \frac{38}{2} \) = 19. The radius of circle is 19 units. Do you want to score well in your Math exams? Then, you are at the right place.

WebThe circumference of a circle is 440 yards. Find the diameter and radius of the circle. Solution. Circumference = 2 * π* R = 2πR. 440 =2 * 3.14 * R. 440 = 6.28R. Divide both sides by 6.28 to get, R = 70.06. Therefore, the radius of the circle is 70.06 yards. But, since the diameter is twice the radius of a circle, the diameter is equal to 140 ... WebJan 2, 2016 · Explanation: Diameter is the ratio of the circumference of the circle to the irrational constant 'pi' (3.1415...). Radius is the half of the diameter. D = 2 ×radius and … WebRadius will always equal one half diameter. Diameter is the measurement of a straight line across the center of an object (in this case a wheel). The circumference of a circle is the total distance around its outside. Circumference equals the diameter of the circle times π (pi), which is about 3.14.
