Question

Find the radius and the circumference to the nearest hundredth when d ≈ 3.6 in. Use 3.14 for π. Drag and drop the correct number into each box to complete the answers.

The radius is approximately _ inches.

The circumference is approximately _ inches.

Answer 1

Explanation:

the radius is always half of the diameter.

so, the radius is approximately 3.6/2 = 1.8 in.

and the circumference of a circle is

2×pi×r = d×pi = 3.6×3.14 = 11.304 ≈ 11.3 in.
