Question

Tammy cut several identical strips of purple and pink paper, and then glued them into rings. The radius of each ring is 1.5 inches.

What is the circumference of each ring? Rounded to the nearest 10th.

Answer 1

The circumference of each ring, rounded to the nearest tenth, is approximately 9.42 inches.

Step-by-step explanation:

The circumference of a circle can be found using the formula:

Circumference = 2πr

Given that the radius of each ring is 1.5 inches, we can substitute this value into the formula:

Circumference = 2π(1.5)
= 3π inches

Now, to determine the circumference rounded to the nearest tenth, we can approximate the value of π to be 3.14.

Therefore, the rounded circumference of each ring would be approximately 9.42 inches.

Answer 2

You would multiply 2 by 3.14 times 1.5
