Dane is building a circular table with a circumference of 145 inches (in.). What are the diameter and radius of the table? Use 3.14 for. Round to the nearest hundredth.

Answer 1

First, let's use the formula for the circumference of a circle:
C = 2πr

Given that the circumference is 145 inches, we can plug that in:
145 = 2 * 3.14 * r
145 = 6.28r

Next, divide both sides by 6.28 to solve for the radius (r):
r = 145 / 6.28
r ≈ 23.09 inches

To find the diameter, we know that the diameter is twice the radius:
d = 2r
d = 2 * 23.09
d ≈ 46.18 inches

So, the radius of the table is approximately 23.09 inches and the diameter is approximately 46.18 inches.
