Then this one, c=1/2(half)mr solving for m

And solve the formula for the indicated variable P=a+2b+4c, for a.

\(\displaystyle B=\frac{1}{9} \pi ^2 t\)

2) \(\displaystyle c=\frac{1}{2}mr\)

Multiply both sides by 2.

\(\displaystyle 2c=1*m*r\) or just \(\displaystyle 2c=mr\)

Divide both sides by r.

\(\displaystyle \frac{2c}{r}=m\) so \(\displaystyle m=\frac{2c}{r}\)

3) $P=a+2b+4c$ and solve for $a$

Subtract $2b$ from both sides.

$P-2b=a+4c$.

Subtract $4c$ from both sides.

$P-2b-4c=a$ or $a=P-2b-4c$
