Which composite figure is made up of a cylinder and half sphere

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:

V = (2 / 3) π r³

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 .

V=π(4)²(7)

V = 112π

Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes

V = 128π/3 +  112π

 = 485.9 mm³

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

i agree because i see the other persons thinking is clear
