Answer:
153.94 inches cubed
Step-by-step explanation:
plug in 7 as the radius
the formula is A = πr^2
we know that
the formula to calculate the slope between two points is equal to

in this problem we have

substitute the values in the formula



therefore
<u>the answer is the option</u>

It is the last one because if you go 3 left you have to change the sign to a positive (but it is still a negative) and the 2 remain the same sign so it’s h(x-3)-2
AB is the longest side, so ∠C is the largest angle.
use law of cosine: 16²=9²+12²-2*9*12cosC
216cosC=81+144-256=-31
cosC=-0.14352
C≈98
