Answer:
27.73
Step-by-step explanation:
You do 3.25 x 7.3= 23.725 so you round the 2 up to a 3. So then you do
23.73+ 4.00= 27.73
We need to solve for the radius. So using the "formula" for the surface area, we have
900*pi ft^2 = 4*pi*r^2 divide by pi
900 ft^2 = 4*r^2 divide by 4
225ft^2 = r^2 take the square root of each side
15 ft = r
This should give you tools to answer all the questions.

Answer:
Step-by-step explanation:
Parts + 3($40 labor)=183.30
parts + 120=183.30
parts=63.30 but it includes tax. To find costs of parts before tax you
63.30/1.055=60 so parts are $60
or to solve with one equation:
parts(1.055) + 3($40 labor) = 183.30
parts(1.055) + 120=183.30
parts(1.055)=63.30
Parts = 63.30/1.055
parts = 60
