Answer:To find the volume of a cylinder, we need to know its radius (or diameter) and height.Given:Width (diameter) = 15 cmRadius (r) = diameter/2 = 15/2 = 7.5 cmHeight (h) = 7 cmFormula:Volume of cylinder (V) = πr²hCalculation:V = π(7.5)²(7)V ≈ 3.14159 × 56.25 × 7V ≈ 1233.54 cubic centimeters (or milliliters)So, the volume of the cylinder is approximately 1233.54 cm³ or 1.233 liters.
