C squared = a squared plus b squared so x squared = 8 squared + 6 squared
X squared = 100 therefore x is 10
Answer:
B x= number of adults 480-x = number of adults
V=4πr^3V=4π(11)^3<span>
V=5575.28
22 is the diameter and the radius is half of the diameter </span>
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 :)
