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!

Solve the equation for k.<br> 4k - 2z = 8
lozanna [386]

4k-2z=8

Move -2z to the other side. Sign changes from -2z to + 2z

4k-2z+2z= 8+2z

4k= 8+2z

Divide by 4 for 4k and 8+2z

4k/4= 8/4+ 2z/4

k= 2 +1/2z

Answer: k= 2 +1/2z
