as 3.14

-- approximated
Answer:
v = 2034.72 mm³
Step-by-step explanation:
radius = 18mm
height = 6mm
pi = 3.14
v = πr²h/3
v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm² x 2mm
v = 2034.72 mm³
Answer:
86
Step-by-step explanation:
the rectangle portion is 18*4= 72
1 triangle portion is 1/2bh where the base is 4 and height is 3.5
1/2*14=7
the 2nd triangle as the same proportions, so it is also 7
72+7+7=86
