The ratio A/r² would represent
which is the circumference of a circle divided by its diameter.
You can see this because the area of a circle is
r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
Answer:
168
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use the formula 
to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (
).
So, we can setup an equation:
Solve for z:
Combine like terms
Subtract 200
Divide by 5
Therefore, the value of z = 68.
Answer:
I think 8
Step-by-step explanation:
9/2 and 5/8
