What is the volume of a cylinder with radius 3 units and height 5 units? (2021)

Step 1: Identify the formula for the volume of a cylinder, which is Volume = πr²h.
Step 2: Identify the radius (r) and height (h) of the cylinder. Here, r = 3 units and h = 5 units.
Step 3: Calculate r² (the radius squared). This means multiplying the radius by itself: 3² = 3 * 3 = 9.
Step 4: Multiply the result from Step 3 by the height (h). So, 9 * 5 = 45.
Step 5: Multiply the result from Step 4 by π (pi). This gives us the final volume: 45π cubic units.
