Answer:

Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715

Solve for L:<br> P=2L+2W

Korvikt [17]

Answer:

$L=\frac{1}{2}P-W$

Step-by-step explanation:

Let's solve for L.

$P=2L+2W$

Step 1: Flip the equation.

$2L+2W=P$

Step 2: Add $-2W$ to both sides.

$2L+2W+-2W=P+-2W$

$2L=P-2W$

Step 3: Divide both sides by $2$ .

$\frac{2L}{2}=\frac{P-2W}{2}$

$L=\frac{1}{2}P-W$

Answer:

$L=\frac{1}{2}P-W$

First piece is x
second piece is y. y=4x
third piece is z. z=3y=12x

x+y+z=680
x+4x+12x=680
17x=680. x=40cm y=160cm. z=480cm
