Answer:
4
Step-by-step explanation:
The common ratio r of a geometric sequence is obtained by dividing a term by its preceding term as follows:
1) 4/1=4
2) 16/4=4
for this sequence the common ratio
r=4

Answer:
485.9 mm³
Step-by-step explanation:
The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:
<h3>V = (2 / 3) π r³</h3>
V = 128π/3
The formula for the volume of a cylinder is V = Bh or V = πr²h .
The radius of the cylinder is 4mm and the height is 7mm
Substitute 4 for r and 7 for h in the formula V = πr²h .
<h3>V=π(4)²(7)</h3>
V = 112π
Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes
<h3>V = 128π/3 + 112π</h3>
= 485.9 mm³
