Answer:
D. 59.66
Step-by-step explanation:
The formula is <em>A = ![\pi r^{2}[/tex\ Also the radius is half of the diameter. and [tex]\pi](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%5B%2Ftex%5C%20%3C%2Fem%3EAlso%20the%20radius%20is%20half%20of%20the%20diameter.%20and%20%5Btex%5D%5Cpi)
= 3.14</em>
so we need to find the area's
9 x 9 = 81
81 x 3.14 = 254.34
Next circle.
10 x 10 = 100
100 x 3.14 = 314
Now to find the difference.
314 - 254.34 = 59.66
59.66

Answer:
71°
Step-by-step explanation:
31-3x+19x-5=90
16x=90-26
16x=64
x=4
m<R=19x-5 = 19(4)-5 = 76-5 = 71
Answer:
ABCD is a square and a rectangle, just graph the points to see the shape it makes
I believe it's C.
(Hint: y=mx+b)
M is Slope and B is Y-Intercept.
Answer:
The equation for the amount of dollars pledged in total is f(M) = 2.00M + 7.25, and the amount for just Kiara is f(M) = 0.25M + 5.25
Step-by-step explanation:
The amount they pledge up front is a constant and therefore need to be added to the end of the equation. The amount per mile should be a variable amount. This gets multiplied by the M variable. So we start with the Kiara amount.
0.25 per mile = 0.25M
5.25 pledged = 5.25
Now put them together to get f(M) = 0.25M + 5.25
Do the same with Mark.
1.75 per mile = 1.75M
2.00 pledged = 2.00
Now put them together to get f(M) = 1.75M + 2.00
To get the final total, we add both equations together.
f(M) = 0.25M + 5.25 + 1.75M + 2.00
f(M) = 2.00M + 7.25
