Answer:
pic # 1 answer is B. 81 x pi
pic#3 answer is C. QC
Step-by-step explanation:
pic #1
the formula to find the area of a circle is pi x the radius to the second power
they give you the diameter. (18)
the radius is half of a diameter (d/2)
so 18/3 = 9
9 to the second power (9 x 9) = 81
so your answer is 81 x pi
pic#2
I don't much, but i do know they asking for the radius and since the radius is half the diameter of a circle then QC makes sense in my book.
hope this is helpful.
2/3 is the slope of the line :)
