Question

A circle has a radius of 119.3 millimeters. What is the circumference of this circle? Use 3.14 for pi. Round your final answer to the nearest tenth.

Answer 1

0.74 m

Explanation:

The distance around a circle on the other hand is called the circumference (c).

A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) .

Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).

The circumference of a circle is found using this formula:

C=π⋅d

or

C=2π⋅r

Given r = 119.3 mm

So, C = 2 * 3.14 * 119.3 = 749.2 mm = 0.74 m
