11/01/2019 · Calculating the Diameter of a Circle Using the Radius, Circumference, or Area. 1. If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. Example If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. 2. If you know the circumference of the circle, divide it by π to get the how to keep sand art in place If you're asked to supply the radius of the pipe, the radius is simply half the diameter. So, to continue the example, a pipe with diameter 3.1832 inches has a radius of 3.1832 ÷ 2 = 1.5916 inches. So, to continue the example, a pipe with diameter 3.1832 inches has a radius of 3.1832 ÷ 2 = 1.5916 inches.

**. If the radius of the outer circle Algebra**

Then from here we can use the Pythagorean Theorem to help us find the radius of the big circle. Since the length of the chord is 100, half of that would be 50 and this would be one of the legs of the right triangle, then the radius r would be the length of the other leg of the right triangle. how to find hostname of pc The Radius of the inner circle is 10 cm, half the length of the sides of the Regular hexagon. AC is a side of one of the hexagons and BD is a side Of the second, which is obtained from the first by rotation. (I) Find the area of the inner circle, giving your answer in terms of Ï€.

## How To Find Radius Of Inner Circle

A smaller circle (inner circle) with the radius r = 3 cm and the larger circle (outer circle) with radius R = 5 cm. We used lower case letter r to represent the radius of inner circle and Upper case letter R to represent the radius of outer circle.

- 24/11/2012 · Best Answer: If the area of the annulus and the Bigger radius are known, BC = Big circle, SC = Smaller circle: Area(annulus) = Area(BC) - Area(SC)
- The above image is at one of the corner,but to find out the center and ID and OD, if i use ginput() as three times i cant exactly locate center ,inner and outer edge using mouse pointer and also using reginprops() command,i am not getting the center of the circle but i am getting the center of the image((size(image))/2), also from this regionprops not getting the ID and OD.
