Answer:
Step-by-step explanation:
Use the formula for area of a circle
A = 
The diameter is 8ft, if there was only a line from the middle to the edge of the circle, then it would be radius
The radius is half the diameter so divide 8 by two and you get the radius
Plug in the radius into the formula
A = 
the parenthesis indicate you aren't only squaring the ft, but also the 4
4ft * 4ft = 16
(remember you are also multiplying the unit, in this case feet)
A = 
there aren't parenthesis here, meaning you aren't squaring the 16
A = 50.24
Answer:
c
The answer they want: If you subtract the -2 x from the y side, then you get 4 y= 2 x + 8. Then you divide the entire equation by 4 getting y= 1/2 x + 8. Next, you can either put it in the calculator or you can put the numbers in the equation and solve it.
