What is the formula to find the radius? If the diameter of a circle is known then the formula for radius is diameter divided by 2. If the circumference of a circle is known then the formula for radius is the circumference divided by 2 pi. And if the area of a circle is known then...
The diameter of a circle is the distance across a circle directly through its center. The radius is one half of the diameter in measurement. The radius measures the distance from the very center of the circle to any point on the circle. You can calculate either of the measurements if you...
Circle: In geometry, a circle is an extremely frequent and closed shape. We are capable of determining the circumference and area when we know the radius or diameter. The formulas for the circumference and area are provided below: Circumference: {eq}C=2 \pi r {/eq}, ...
Find the radius of a circle whose area equals the area of a rectangle that measures 2 feet by 11 feet (use {eq}\pi = \frac{22}{7} {/eq}). The Area of a Circle: The area of a circle of radius {eq}R{/eq} is given as {eq}A...
