Answer:
A = 121 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi*r
22 pi = 2 * pi *r
Divide each side by 2 pi
22 pi / (2 pi) = 2 pi r / (2pi)
11 = r
Now find the area
A = pi r^2
A = pi (11)^2
A = 121 pi in^2

Solution:
Given equation is
.
To solve the equation by step by step.
Step 1: Given
![$\frac{8}{3}=3c+\frac{5}{3}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B8%7D%7B3%7D%3D3c%2B%5Cfrac%7B5%7D%7B3%7D%24)
Step 2: Combine like terms together.
Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.
![$\frac{8}{3}-\frac{5}{3}=3c$](https://tex.z-dn.net/?f=%24%5Cfrac%7B8%7D%7B3%7D-%5Cfrac%7B5%7D%7B3%7D%3D3c%24)
Step 3: Subtract the fractions in the left side.
![$\frac{3}{3}=3c$](https://tex.z-dn.net/?f=%24%5Cfrac%7B3%7D%7B3%7D%3D3c%24)
⇒ ![1=3c$](https://tex.z-dn.net/?f=1%3D3c%24)
Step 4: Divide both side of the equation by 3, we get
![$\frac{1}{3} =\frac{3c}{3}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20%3D%5Cfrac%7B3c%7D%7B3%7D%24)
![$\frac{1}{3} =c$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20%3Dc%24)
Hence, the answer is
.
Answer:
lol just found it.
Step-by-step explanation:
2.50$ is the better deal. If you times 0.70$ to 5 it is 3.5$ which is more expensive
i believe the answer is B
but i could always be wrong :(
