please mark me brilliant

Answer 2

Answer:

Step-by-step explanation:

Answer:-
a) The Soccerfield's Length: Width is 5:3
    So....................................90: Width =  5:3  
Therefore............................5 X Width = 3 X 90 = 54
                                                Width = 270/5
                                                Width = 54 metres
b) The formula for finding the radius of a circle is C/2 X Pi [C=Circumference]

                              Therefore Radius= 57.5/2 X Pi
                                                           = 9.15140922778
So Approximately.....................Radius= 9.15 metres
