Answer:
Option C
Step-by-step explanation:
Exteriore angle property: Exterior angle equals the sum of opposite interior angles.
∠I = 77° + 56°
     = 133°

The formula, solved for r is r = ∛(9V/π)
<h3>Subject of formula </h3>
From the question, we are to solve for r is the given formula
The given formula is 
V = 1/9πr³
Multiply both sides of the equation by 9 to get 
9V = πr³
Now, divide both sides by π
∴ r³ = 9V/π
r = ∛(9V/π)
Hence, the formula, solved for r is r = ∛(9V/π)
