Step-by-step explanation:
Remember, to find the area of a circle, you need to multiply pi by the radius squared
The area, 'A', of the circle is 153.86 inches squared
'π' is pi, an irrational number with a value of approximately 3.14
'r' is the radius, which is what we are solving for here
We plugged our information into the A=πr2 formula
We get "r=7", which means the radius of the circle is 7 inches!
Since you know Z = 2, you can plug it into:
Y = 5 · Z²
Y = 5 · (2)²
Y = 5 · 4
Y = 20
Now that you know Y = 20, you can plug it into:
X = 2 + 5Y
X = 2 + 5(20)
X = 2 + 100
X = 102
Now that you have X, plug it into "2+2X=?"
2 + 2x = ?
2 + 2(102) = ?
2 + 204 = ?
206 = ?
