Answer:
First know this,
The volume V of a cylindrical barrel is given by the formula. V = πr2h, where r is the barrel's radius and h is the barrel's height.

Rewrite the equation as πr2h=V π r 2 h = V . Divide each term by πr2 π r 2 and simplify. Divide each term in πr2h=V π r 2 h = V by πr2 π r 2 .

Answer:
It/p= r
Step-by-step explanation:
divide p and t out of the r and multiply by the recipricol
