Accepted Solution
A:
Answer:78.50Explanation:if the Radius(not area) is 5, you would do this equationA=Οr^2 as in area=pi x radius^2so you would simplify this intoA=(3.14)(5)^2so then you would square 5 which becomes 25. the problem should look like this:A=(3.14)(25)you would then multiply 3.14 by 25 which equals 78.50 orA=78.50then you would round to the nearest tenth and since 0<5 it would be 78.5 orA=78.5
