A = pi(r^2)
1. Calculate radius:
r = d/2, so r = 18
2. Enter variable into equation
a = pi(r^2)
becomes a = 3.14(18^2)
3. Solve
a = 3.14(324)
a ~= 1018 in2
4. Convert to feet
1018/12 = 84 ft2
5. Multiply by unit rate
84(3.5) = $294
It will cost $294 to paint the sign.
X = 2.
Set up your equation like this:
3x + 4x = 14
7x = 14
x = 2

Answer:
true
Step-by-step explanation: The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
