Answer:
9π - 9
Step-by-step explanation:
Depends on what the question stated was pi (π). The area of the circle is 9(3 squared) * π. the shaded area is the area of the circle - the area of the triangle. The area of the triangle is base * high / 2. If the diameter of the circle (6) is what we use as the base, then 3 would be the high, making the area 9. This means the shaded area would be 9π - 9.

This one has two parts, first we have to find out the speed to drive 660 miles in 12 hours. Divide 660 by 12 to get the speed of 55 miles per hour, that is your rate for the next part.
Next we need to find out how long it will take to drive 495 miles at the same pace of 55 mph.
Do the same thing 495/55. That will give you your final answer.
495/55= 9
It will take him 9 hours to drive 495 miles at a rate of 55 mph.
First, substitute the values of the variables into the equation:
2x+(3)(6)=36
Then, you must simplify,
2x+18=36
Then, you must factor out 18 to leave x and its coefficient alone on one side of the equation:
2x+18-18=36-18
Then you must simplify the equation and divide by 2 on both sides of the equation to factor out the coefficient:
2x/2=18/2
Then you will simplify and you will find the value of x:
x=9
