Answer:
Radius, r = 10 cm
Radius, r = 10 cmWe know, Circumference = 2πr=2×π×10=20π cm
The circumference of the circle is
20π cm or about 62.8 cm.
Here's how I did it:
The formula for a circumference of a circle is 2πr , where r is the radius. We can plug our known value of the radius ( 10 cm) into the formula and solve.
2π 10=20π cm or about 62.8 cm.
Explanation:
The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle.
