Answer:

50.24 cm^2

Step-by-step explanation:

The formula for the area of a circle is A = πr^2

The radius is half of the diameter so r = 4

So now you can solve:

A = 3.14(4)^2

= 50.24 cm^2

Step-by-step explanation:

x ------> the entire Stefanie's allowance

we know that

She spends on clothes (1/2)x

\frac{1}{2}x-\frac{1}{6}x=\frac{2}{6}x

Simplify

\frac{1}{3}x

therefore

She spends 1/3 more on clothes that he does on movies

Solve for n using the additive identity property.
tangare [24]

<em>The answer is:</em>

\boxed{n=5}

<h2>Explanation:</h2>

The additive identity property states that if you add any real number to zero or add zero to any real number, you will get the same real number back. In other words:

a+0=0+a=a \ For \ any \ real \ number \ a

Here we have that:

5+0=n

So by the mentioned property:

5+0=0+5=5

In other words:

\boxed{n=5}
