Answer:Here's how to find the volume of a cylinder:Formula:The volume of a cylinder is calculated by multiplying the base area by the height. - Volume (V) = Base Area (B) * Height (h)Given:Base Area (B) = 18 cm²Height (h) = 5 cmCalculation:V = 18 cm² * 5 cmV = 90 cm³ Therefore, the volume of the cylinder is 90 cm³.
