Answer:

diameter = 49 units

Explanation:

The fromula of a circumference of a circle:


C=2\pi r

r - radius

or


C=d\pi

d - diameter

Use the second formula.

Substitute the value of circumference


C=153.86


d\pi=153.86

use the approximation of number pi:
\pi\approx3.14


3.14d=153.86 divide both sides by 3.14


d=49
