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:
3.14159
Step-by-step explanation:
This number is pi. Pi goes on for millions of digits on end.
Step-by-step explanation:
Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
<span>So we can plug in '4W' for 'L' in the first equation.</span>
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>
Jacob has the faster time because if you make the fractions equal you would make the denominators equal by rounding 3/4 to have a denominator of 12 making it 9/12 which is larger then 5/12 making Daniel's time slower then Jacob's.
The answer is -4 because -4 times -3 equals -12
