C = 2*pi*r
So, C = pi*d
106.76 = pi*d
106.76/pi = d
d = ~33.98
Answer:
Answer C is correct
Step-by-step explanation:
-200(3/4) = -600/4 = -150 ft
Answer:number of cupcakes sold is 13
Number of cookies sold is 27
Step-by-step explanation:
Let x represent the number of cupcakes that Jane sold.
Let y represent the number of cookies that Jane sold.
Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day, Jean had sold $42.75 worth of cookies and cupcakes.
This means that
2.25x + 0.5y = 42.75 - - - - - - - - - -1
she sold 40 cupcakes and cookies combined, it means that
x + y = 40
Substituting x = 40 - y into equation 1, it becomes
2.25(40 - y) + 0.5y = 42.75
90 - 2.25y + 0.5y = 42.75
- 2.25y + 0.5y = 42.75 - 90
- 1.75y = - 47.25
y = - 47.35/-1.75
y = 27
x = 40 - y
x = 40-27 = 13

Answer:400 miles per hour
Step-by-step explanation:
Let w = speed at which the plane travelled west
Let s = speed at which the plane travelled south
Distance moved in 5 hrs heading west = 5*w = 5w
Distance moved in 4 hrs heading south = 4*s = 4s
Total distance, 3444= 5w + 4s
w = s + 39( 39 miles/hr faster)
5(s+39) + 4s = 3444
5s + 195 + 4s = 3444
9s = 3249
s = 361 miles per hour
w = s + 39 = 361 +39
= 400 miles per hour
Hey!
The formula for finding volume of a cylinder is: π · r² · h
![r = 8 \\ r^{2} = 8 \times 8 = 64](https://tex.z-dn.net/?f=%20r%20%3D%208%20%5C%5C%20r%5E%7B2%7D%20%3D%208%20%5Ctimes%208%20%3D%2064%20%20)
![h = 3](https://tex.z-dn.net/?f=%20h%20%3D%203%20)
Now multiply
![\pi \times 64 \times 3 = 192\pi](https://tex.z-dn.net/?f=%20%5Cpi%20%5Ctimes%2064%20%5Ctimes%203%20%3D%20192%5Cpi%20%20)
<em>Your answer is B)192π units³</em>
Good luck and hope this helps! :)
