Answer:
9 inches
Step-by-step explanation:
Volume of a cylinder = πr^2h, where π = 3.14, r is the radius and h is the height of the cylinder.
11,445.3 = 3.14 × r^2 × 45
11,445.3 = 141.3 × r^2 Divide both sides by 141.3
r^2 = 81 Take the square roots of both sides
r = √81
r = 9 inches
Therefore, the radius of the cylinder = 9 inches
