2) The last option.
Step-by-step explanation:
1) f(x) is greater on the interval (0,3), which is opened, because if you substitute
you obtain the following result:

2) If
, you obtain that:

Therefore: 
1) area of a cicular pool
area of a circle=πr^2 d=2.5 then r=2.5/2
A=3.14 *(2.5/2)^2
A=4.906m^2 A=4.9m^2
2) arae of a coin
<span>(if i read it right d=15mm?)
</span>A=πr^2 d=15 then r=15/2
A=3.14*(15/2)^2 =176.6mm^2
Rest all are same problems u try to solve it
