Answer:
Options A-C-F
Step-by-step explanation:
we know that
<em>The circumference of a circle is equal to</em>
or 
where
D is the diameter and r is the radius
therefore
or 
The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius
<em>The area of the circle is equal to</em>

therefore
The number pi is the ratio Area - radius squared
Equation: (70 + 70*.05) + (580 + 580*.07) + (620 + 620*.10) = Total Spent
Solving for this gets you $1320.30.
Answer:
Ab^2 = CA^2 + BC^2
8^2 = 6^2 + a^2
64 = 36 + a^2
64-36 = a^2
28 = a^2
square root of 28 = square root of a^2
5 ,29 = a
5 = a
Divide 3 by 8! So your answer would be 0.375! :)
