Answer:
<h2>

</h2>
Step-by-step explanation:
s = πrl + πr²
First move πr² to the left side of the equation
We have
πrl = s - πr²
Divide both sides by πr to make l stand alone
That's
<h3>

</h3>
We have the final answer as

Answer:
Multiply the width to the length
Step-by-step explanation:
There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
The formula for slope is y=mx+b
so if you re arrange the equation from 8y-16x=12
to 8y=16x+12
the slope will be the coefficient of x =16
