Answer:

50 gallons of red

30 gallons of blue

Step-by-step explanation:

5 parts of the whole must be red, 3 parts of the whole must be blue, and there are 5+3=8 parts in total.

A=4ℼR2 solve for R SHOW ALL STEPSSSSSSSSSSSSS

GuDViN [60]

Given problem;

A = 4 π R²

To solve for R, we have to make it the subject of the expression.

Since

A = 4 π R² , follow these steps to find R;

Multiply both sides by $\frac{1}{4\pi }$

A x $\frac{1}{4\pi }$ = $\frac{1}{4\pi }$ x 4 π R²

$\frac{A}{4\pi }$ = R²

Then find the square root of both sides

√R² = $\sqrt{\frac{A}{4\pi } }$

R = $\sqrt{\frac{A}{4\pi } }$

The solution is $\sqrt{\frac{A}{4\pi } }$
