The diameter of a circle is 18 inches. What is the length of a 90° arc?

Alona [7]

Answer:

AHH! Geometry!

14.1375

Step-by-step explanation:

So to get the answer, we are going to have to make a "factor"

We first do this:(Circles have an angle of 360)

$\frac{90}{360} =\frac{1}{4}$

This tells how long the arc is in comparison to the circumference!

So let's solve the circumference!

$P=D\pi \\P=18\pi \\P=About 56.55$

Now, Multiply!

$56.55*\frac{1}{4} = 14.1375$

There we go!

Hope this helps!

See Ya!
