x - the number of DVDs
<span>You can buy DVDs at a local store for $15.49 each:
15.49x
</span><span>You can buy them at an online store for $13.99 each plus $6 for shipping:
13.99x + 6
</span><span>How many DVDs can you buy for the same amount at the two stores:
</span>15.49x = 13.99x + 6
15.49x - 13.99x = 6
1.5x = 6
x = 6 : 1.5
x = 4
Hello there!
Surface Area = 4pir^2
First, we need to find our radius, since we have our diameter all we need to do is divide it by 2. That means, 10 divided by 2 equals 5.
Our radius is 5.
Now, we can plug it into the formula.
4(3.14)(5^2)
4(3.14)(25)
4(78.5)
4(78.5) = 314
Now, convert into pi.
314 = 100pi or 100Π
