A:
Answer:r = (11√π)/πStep-by-step explanation:V = πr²h We are given V = 1089, and h = 9. Plug them into the formula and simplify1089 = πr²(9) 121 = πr² (divide by 9 on both sides) 121/π = r² (divide by π on both sides) √(121/π) = r (take the square root of both sides) Now simplify √(121/π) (√121)/(√π) 11/√π [11(√π)]/[(√π)(√π)] (11√π)/πso r = (11√π)/π
