Find the radius if you know the circumference
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. WebIf the diameter is 12 then the circumference is 12𝝅 𝝅 is generally difficult to calculate, since it goes on forever you can write it in terms of 𝝅 (12𝝅). You could also times the diameter by 3.14 to estimate it. Example: If the diameter is 12 then the circumference is 37.68. Hope This Helps! ( 3 votes) james.igohe 3 years ago

WebJan 16, 2024 · If you have no idea what the radius or diameter is, but you know the circumference of the circle, C, you can still find the area. Area and circumference formula Circumference (the distance around the circle) is found with this formula: C=2\pi r C = 2πr That means we can take the circumference formula and "solve for r ," which …
WebKnow the radius? Then you can use the formula for the circumference of a circle to get the answer! Just plug the value for the radius into the formula and solve. This tutorial shows you how! Keywords: circle find circumference radius pi multiply solve for circumference Background Tutorials Decimal Operation Problems How Do You Multiply Decimals? WebWell, we know that the diameter times pi, we know that pi times the diameter is equal to the circumference; is equal to 10 meters. So to solve for this we would just divide both sides of this equation by pi. The diameter would equal 10 meters over pi or 10 over pi meters. And that is just a number.
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 by 2 and times it by pie and then you get the circumference.
