Question

One circle has a 96 cm diameter and another circle has a 295.16 cm circumference. Which circle has a larger radius?

Answer 1

Answer: The first one.

Explanation:

One circle has a 96 cm diameter

and another circle has a 295.16 cm circumference.

Which has a larger radius?

Radius of the first circle is 48 cm.

Radius of the second circle is 47 cm

The first circle has a larger radius.

Answer 2

Circle one

Explanation:

First we can name the circle with a 96cm diameter circle one, and the circle with the 295.16 circumference circle two.

To do this we need to find the diameter of the circle with the 295.16 circumference.

Circumference is πd so to reverse that we need to divide the circumference by π.

We can round π to 3.14 to perform this.

295.16/3.14=94

The diameter of the second circle is 94.

Radius is half the diameter. We can find it by dividing diameter by 2.

Circle one: 96/2=48

Circle two: 94/2=47

Therefore, circle one (the circle with a 96 diameter) has a larger radius.
