What is the radius of a circle that has a circumference of 3.14 meters? Solution: Circumference of a circle = 2ПҖr. Given, circumference = 3.14 meters. Therefore, 2ПҖr = Circumference of a circle. or, 2ПҖr = 3.14. or, 2 Г— 3.14r = 3.14, [Putting the value of pi (ПҖ) = 3.14]. or, 6.28r = 3.14 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. The radius of the circle is 3.5 feet.

Circumference of circle = 2ПҖr. While ПҖ = 3.14. By putting values C = 2 * 3.14 * 3.5. C = 22 c m. So, in this case, when we are given the radius, we can calculate circumference by above-given circumference formula. But if there is given diameter, the circumference formula will be: C i r c u m f e r e n c e = ПҖ d R = radius of the circle. However, if you are trying to determine the area of a circle as well as its radius, you should use the following formula: A = ПҖ * R^2. where A = area of the circle; ПҖ = pi = 3.14; R = radius of the circle. #3: Determining The Circumference Of A Circle Manually The circumference can be found by the formula C = ПҖd when we know the diameter and C = 2ПҖr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6ПҖ meters or approximately 18.8495559 m. Now we multiply that by $$\frac{1}{5}$$ (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters Take ПҖ = 3.14. Ans: Given, the radius of wheels of a bicycle ( r) = 50 cm. We know that the circumference of a circle = 2 ПҖ r. = 2 Г— 3.14 Г— 50 cm. = 314 cm. To find the number of revolutions of the wheel, divide the distance covered by the circumference of the wheel. To convert 157 metres to cm multiply by 100

Circumference of a 5 Inch Diameter Circl

The formula for the radius of a circle based on the length of a chord and the height is: r = L2 8h + h 2 r = L 2 8 h + h 2. where: r is the radius of a circle. L is the length of the chord. h is the height of the chord. A useful application of the math construct is in construction where the formulas computes the radius of an arch The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius. \begin {align*}C = 2 \pi r\end {align*} If you are given the circumference but not the radius or the diameter, you can still solve for one or the other using these formulas
