Answer:
C = 25.12 , A = 50.24
Step-by-step explanation:
![C = \pi d\\A = \pi r^{2}](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20d%5C%5CA%20%3D%20%5Cpi%20r%5E%7B2%7D)
C = 8 * 3.14 = 25.12
A = (4*4) * 3.14 = 50.24
Answer: -5
Step-by-step explanation: 2 + -11 = -9 and subtract -4 from it since it’s the sum of 2 + -6. -9 - -4 is -9 + 4 so -5
Answer:
Let P represent the number of pies sold and J represent the number of juices sold.
a)
The first equation for the sum of the sales:
P + J = 79
P = 79 - J
Next, for the sum of the amounts earned:
1.65P + 1.36J = 118.17
Substituting P,
1.65 (79 - J) + 1.36J = 118.17
J = 42
Using this value of J,
P = 79 - 42
P = 37
b)
Mr. Sanchez's class earned: 1.65 x 37 = $61.05
Mr. Kelly's class earned: 1.36 x 42 = $57.12
So Mr. Sanchez's class earned more money.
c) Mr. Sanchez's class earned:
61.05 - 57.12
= $3.93 more than Mr. Kelly's class
