Answer:
volume= 170 cm^2
Step-by-step explanation:
The volume of a cylinder is V=π(r)^2(h),V=pie(radius squared) height. The radius is 1/2 the size of the diameter. The diameter is 6 cm, so the radius is 3 cm. we know the height of the cylinder is 12 cm. Plug in the variables. V=π(3)^2(12). if we solve this equation using PEMDAS, we get 339.12 cm^2, this is the volume for the total cylinder. However, Keenan drank half of the cylinder. So, 339.12/2=169.56 cm^2, or 170 cm^2 if rounded to the nearest number.
