Answer:
Step-by-step explanation:
Use the formula for area of a circle
A = [tex]\pi r^{2}[/tex]
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 = [tex](4ft)^{2} \pi[/tex]
the parenthesis indicate you aren't only squaring the ft, but also the 4
4ft * 4ft = 16[tex]ft^{2}[/tex]
(remember you are also multiplying the unit, in this case feet)
A = [tex]16ft^{2} \pi[/tex]
there aren't parenthesis here, meaning you aren't squaring the 16
A = 50.24[tex]ft^{2}[/tex]
