Answer:
34.7791 [unit²].
Step-by-step explanation:
1) area of the circle is:
πr²;
2) area of the regular polygon is:
6*r²√3*0.25=1.5√3r²;
3) the required area:
πr²-1.5√3r²=r²(π-1.5*√3)=64*(3.1415-1.5*1.7321)=34.7791
Answer:
Step-by-step explanation:
I would write an inequality at this point
The variable would be the amount of hours(x) it would take for the costs to tip the scales
9.75x-10≥7.25x
-10≥-2.5x
4≥x
It would take them 4 hours for the costs to be equal, so anything higher than this would work
75/15 is one of them. Not sure about the rest
