WebFind the diameter and the radius of a circle with a circumference of 465 cm. Give the answer to the nearest centimetre. Use π = 3۰142 or the π button on a calculator. 2 of 7 WebNov 28, 2024 · Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. \(7\divide 2=3.5\) The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
