Answer:
24 π square inches
Step-by-step explanation:
The area of a circule is give by the formula A = π r²
Since we have a angle of 60 degrees, that represent 1/6th of the whole area (60 / 360 degrees).
A circle = π * 12² = 144 π square inches
Area of the portion representing 60 degrees of the circle, can easily be calculated with a cross-multiplication:
x = 144 π / 6 = 24 π square inches
The cost for a party here is the base fee, plus charges for any additional guests.
So we know for a 15-person party, the price is going to be $100. That's a flat (constant) cost.
We know that for each additional person, we add $12. So for
more people, the cost is $
.
Since 100 is constant here, we make that our y-intercept. Even with no additional guests, the cost is still $100.
We add to write
. 12 is the constant rate of change (slope).
