Private Pesticide Applicators Practice Exam – Practice Test & Study Guide

The radius of a circle is defined as half of its diameter. In this case, you are given a diameter of 10 feet. To find the radius, you simply divide the diameter by 2.

Calculating this gives you:

10 feet ÷ 2 = 5 feet.

This means the radius is 5 feet, which aligns perfectly with the definition and calculation based on the relationship between diameter and radius. Understanding this fundamental relationship is crucial in geometry, especially when working with circles.
