A = pi * r^2
A = 3.14 * 50^2 
A = 7,850 square miles (area of the 50 mile broadcast signal)

A = pi * r^2
A = 3.14 * 75^2
A = 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 = 9,813 square miles greater

Hope this helps :)

A customer ordered a product online for $299 and was charged an additional $10 for shipping and handling. The customer received

swat32

Answer:

$192.4

Step-by-step explanation:

First, we'll work out what the customer had to pay before tax.

That's

$299+10-99-25\\=185$ (USD)

4% of 185 is 7.4,

So the customer paid

$185+7.4\\=192.4$ (USD)
