Step-by-step explanation:
Radius is half of the diameter
Circumference is 2*pi*radius
Area is pi*radius^2

C (circumference)=64.72
and A (area)=333.29
feel free to ask more questions :)
Answer:
42.9
Step-by-step explanation:
20% of 50 is 10
so its 40
40 + taxes
40 + (40*.0725)
1/5 of 20 is 4.
2/5 of 20 is 8.
Therefore, Ron used 8 apples to make his pies.
Answer:
infinite solution
Step-by-step explanation:
because Y = 7(x + 2) and y = 7x + 14 are the same
y = 7(x+2) = 7x + 14
eliminate to see
y = 7x + 14
-(y = 7x +14)
= 0 = 0 + 0
so it is infinite solution
