Question

The radius of a circle with an area of 60 square centimeters is represented by the expression square 60 divided by pie centimeters. What is another way of expressing the radius

Answer 1

In term of the diameter

Explanation:

For every circle, the area is given by:

$A=\pi r^2 \\ \\ \\ Where: \\ \\ r:Radius \\ \\ A:Area$

Isolating r, we get:

$r=\sqrt{\frac{A}{\pi}} \\ \\ \\ Where:A=60cm^2 \\ \\ r=\sqrt{\frac{60}{\pi}} \\ \\ r=4.37cm$

Another way of expressing the radius is in function of the Diameter (D). So the radius is half the diameter, in other words:

$r=\frac{D}{2}  \\ \\ \\ Where: \\ \\ D=2(4.37) \\ \\ D=8.74cm$
