Answer 2

T
o find how many meters square a circle has, you need to first find the formula for area of a circle
area of a circle = Pie*r^2
so you input your data as follows
A = 3.14 * (3.5 m)^2
A = 38.465 m^2 <--(meters squared)
then you need to find how much it would be for each of these squared meters
$$$ = 38.465 * $3.25
$$$ = 125.01125 = $125.01

so I would pick D
