Answer:
The answer is 236.52.
Step-by-step explanation:
First you want to figure out the radius of the semi circle so you take the length of 12 and divide it by 2. Then you want to use the formula for area of a circle 3.14 times radius squared and divide that by 2 and add 12x15 to get your answer.
How does it need solved? By graphing? Substitution?
Answer:a: y=4.5+0.75x
B: y=2.5+1.25x
C: 7.5
(2/3)^3 = (2/3) times (2/3) times (2/3) = 8/27
