Alarger circle has a circumference of 30. a smaller circle has a circumference of one third of that. find the radius of the smaller circle.

The radius of the smaller circle is 2 (approximately).

Step-by-step explanation:

Given:

Circumference of larger circle is 30, and circumference of smaller circle is one third of that.

So, to get the radius of the smaller circle, let us calculate its circumference.

.

Now, putting the formula of circumference(c) to find the radius(r):

⇒        (π = 3.14)

⇒

by dividing both sides by 6.28 we get:

⇒

⇒

⇒.

Therefore, the radius of the smaller circle is 2 (approximately).
