Answer:
a) 63.8 in³
Step-by-step explanation:
so the cylinder is 12 inches high
πr²h = π(1.25)²(12) = 58.90 in³
cone is 3 inches high
1/3πr²h = = 1/3π(1.25)²(3) = 4.91 in³
58.90 + 4.91 = 63.81 in³
Answer:
63.8 in
Step-by-step explanation:
the formula of te volume of the cone is : πr²h/3
the height of te cone is the height of the tip
V=π(1.25)² * 3/3
V1=4.91( rounded to the nearest hundredth)
volume of the cylinder =πr²h ( the height of cylinder=25-3=23)
V2=π(1.25)²*12
V2=58.90
V1+V2=4.91 +58.90=63.81 ≅63.8
