(Hint: use radius formula when the diameter is known) Solution: We will use the radius formula when the diameter of a circle is given. Which is expressed as. Radius = Diameter/2. D = 24 inches. R = 24/2 = 12 inches.
WebFeb 3, 2024 · 2. Divide the diameter by two. A circle's. radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm. In math formulas, the radius is r and the diameter is d. You might see this step in your textbook as. r = d 2 {\displaystyle r= {\frac {d} {2}}} . WebFeb 9, 2024 · r, or the circle's radius, is the length of a line that joins the center point with any point lying on the circle. You can find it with the following formulas: If you know the diameter of the circle: r = d / 2. If diameter and area are unknown: r = c / 2π. If diameter and circumference are unknown: r = √ (a / π)
WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius … WebFeb 17, 2016 · A. In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units. C = 2 π r = 2 π × 5 = 10 π units. Q.
