Question

"latex-formula">the radius of the circle is 14 miles what is the circles area using 3.14 for pi

Answer 1

Answer:

$Area = 615.44 miles$ is the circles area.

Explanation:

Before we answer the math problem, let's examine what we know so far.

$\left[\begin{array}{cc}raidus =14miles\\Diameter = 28miles\\circumference = 87.92 miles\end{array}\right]$

In Terms of Pi π

circumference = 28 π mi

Area = 196  mi^2

$Diameter - Steps$ - How I found the diameter ( R stands for Radius )

$d = 2r\\d = 2 *14\\d = 28$

$circumference - Steps$ - How I found the circumference

$C = 2\pi r\\C= 2 *\pi *14 \\C= 28\pi \\C = 87.92$

$Area-Calcuating$ ( The circules area )

$A =\pi r^2\\A=\pi *14^2\\A =196\pi \\A=6.15.44miles$

So, $Area = 615.44 miles$ is the circles area.

Hope this helps! :D
