Jeffrey is buying mulch for a circular flower garden with a diameter of 12 feet. The layer of mulch needs to be 4 inches thick. What is the volume of mulch needed for the flower garden? A) 37.7 ft3 B) 113.1 ft3 C) 452.4 ft3 D) 651.4 ft3
Well you need to do V= pi(r)h squared so Diameter of 12 divided by 2 will get you r so 6 3.14Γ6squared is equal to 3.15Γ36 which is 113.04 then times height of 4 gives you 452.4 so C)
