WebThe circumference of a circle is equal to Pi π π times the diameter d d. Since the diameter d d is equal to 2 2 times the radius r r, the formula for circumference using radius is 2πr 2 π r. Substitute the value of the radius r = 7.5 r = 7.5 into the formula for the area of a circle. Pi π π is approximately equal to 3.14 3.14. WebFeb 17, 2016 · The formula for the circumference of a circle is C = π × d, or it can be written as C = 2 × π × r. Either one works! Now, you may be asking, “Well where did pi come from, and why do we all the sudden get the circumference if we multiply said pi by our diameter? Who decided that?” If you are not asking that question…
What is the circumference of a circle with diameter 23 cm?
WebAug 2, 2024 · Just divide the circumference by π to find the diameter. For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately … WebThe 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.
