<h2>Area of Shaded</h2>

Find the area of the shaded area shown.

<h3>Solution:</h3>

A = s²
A = 32cm
A = 32cm x 32cm
A = 1024
A = 32/4/2
A = 32 ÷ 2
A = 8
A = 8 ÷ 2
A = 4

So in the inscribed circle there are 16.

A = 16 radius ²
A = 16 x 4r²
A = 4 x 4
A = 16
A = 16π x 16
A = 256π
A = 256 x 3.14
A = 803.84
A = 1024cm - 803.84
A = 220.16cm²

What do I need to find?

Your answer is correct.

What information do I need to use?

100% = 240 miles, she has already driven 15% of 240, so she has driven x miles.

How will I use the information?

Set up a proportion. If she has already driven 15% out of 100% of the distance, then you should write $\frac{15}{100}$ for the first fraction. This is proportional to $\frac{x(miles)}{240(miles)}$ . This means that $\frac{15}{100} = \frac{x}{240}$ . Wait, but this is confusing. How on Earth do we solve it? Let's take a closer look. If $\frac{x}{240}$ is supposed to equal 15/100, then this means that x/240 divided by 15/100 should give us the answer. So, even though it looks complicated, all you have to do is cross multiply like this:

$\frac{15}{100} = \frac{x}{240} --> 240 * 15 = 100x --> 3600 = 100x$

Now isolate x:

$\frac{3600}{100} = \frac{100x}{100}$

So x = 36, which means she has already driven 36 out of 240 miles. Lucia still has to drive 204 miles to reach her destination.

1.) In this case, 56 = 100% and 25% of the sandwiches were tuna. This means that 75% of the sandwiches were not. If $\frac{25}{100} = \frac{x}{56}$ and you use the same method above, x is equal to 14. If 14 is 25% then that means the other 75% = 14 * 3. So 42 sandwiches were not tuna.
