Use a metric ruler.
The radius of a circle is the distance from the center of the circle to any point on its circumference. If the radius of a circle is given as 26.4 cm, then that means the distance from the center to the edge of the circle is 26.4 cm. This measurement is constant for any point on the circle, as all points on the circumference are equidistant from the center.
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
WOW really? It would be 20cm
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The radius of the circle is: 9.549 cm
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
A scale ie required to measure the area of a circle. We need to measure the radius of that Circle and then we can put this radius valve in below mwntioned formula & can calculate the area. A=3.14*r*r where r is radius in Cm. A is are in cm square. Hemant gautam +919099921329
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
If the circumference of a circle is 12 cm the radius is: 1.91 cm
