The circumference of a circle is 219.8 inches. What is the circle's radius?
Use 𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
To find the radius of a circle given its circumference, we can use the formula circumference = 2πr, where r is the radius.
Given:
Circumference = 219.8 inches
π ≈ 3.14
Using the formula:
219.8 = 2(3.14)r
Divide both sides by 2(3.14):
r = 219.8 / (2 * 3.14)
r ≈ 34.98
Rounding to the nearest hundredth:
The circle's radius is approximately 34.98 inches.
