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:
I think the answer is 5
Step-by-step explanation:
3+2=5
Answer:
x=20
Step-by-step explanation:
Let's solve your equation step-by-step.
4x−4+3x−2+2x+6=180
Step 1: Simplify both sides of the equation.
4x−4+3x−2+2x+6=180
4x+−4+3x+−2+2x+6=180
(4x+3x+2x)+(−4+−2+6)=180(Combine Like Terms)
9x=180
9x=180
Step 2: Divide both sides by 9.
9x
9
=
180
9
x=20
Answer:
x=20
the 2 numbers are 8 and 40
40*2 = 80 +8 = 88
