A = pi * r^2
<span>A = 3.14 * 50^2 </span>
<span>A = 7,850 square miles (area of the 50 mile broadcast signal)
A = pi * r^2
A = 3.14 * 75^2
A = </span>17,662.5 = 17,663 square miles (area of the 75 mile relayed signal)
Now we just need to subtract the 50 mile signal from the 75 mile signal, so:
17,663 - 7,850 = <span>9,813 square miles greater
Hope this helps :)

47.5% in decimal form is 0.475.
Since the price was increased, we add 1 to 0.475 to get 1.475.
80 * 1.475 = 118
Another way to solve this is to multiply 80 by 0.475, which is 38, then add it to 80.
The retail price of the shoes is $118.
Answer:
B= 13
Step-by-step explanation:
10x-5= 180-(4x+3)
10x-5=180-4x-3
10x-5+3=180-4x
14x-2=180
14x= 180+2
14x= 182
x=182/14
x=13
The answer is D 33 because it starts by adding 1 and then doubles the amount added every time<span />
