The figure is made up of a cylinder and a cone. What is the volume of the composite figure? Use 3.14 for Pi. Round to the neares

Delvig [45]

Answer:

The volume of figure is 310.86 cm³

Step-by-step explanation:

First, you have to calculate the volume of cone and cylinder seperately by applying the formulas :

Cone,

$v = \frac{1}{3} \times \pi \times {r}^{2} \times h$

$let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 9$

$v = \frac{1}{3} \times 3.14 \times {3}^{2} \times 9$

$v = 84.78 \: {cm}^{3}$

Cylinder,

$v = \pi \times {r}^{2} \times h$

$let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 8$

$v = 3.14 \times {3}^{2} \times 8$

$v = 226.08 \: {cm}^{3}$

Next, you have to add up both volumes as the figure are made from cone and cylinder :

$v = 84.78 + 226.08$

$v = 310.86 \: {cm}^{3}$

P = 2n P - 5 = 1.5n What value of n makes the system of equations true?

alexira [117]

Answer:

n=10

Step-by-step explanation:

P = 2n

P -5 = 1.5n, substitute P

2n -5 = 1.5n, subtract 1.5n and add 5 to both sides

2n -1.5n = 5, combine like terms

.5n = 5, divide both sides by .5

n= 10

MA_775_DIABLO [31]

Answer:

John needs 217 tiles.

Rate of change is 1.9 tiles per square foot

Step-by-step explanation:

Hallway area=3•38=114 ft²

Rate of change=190/100=1.9 tiles/ft²

Tile total=

T=area•rate

=114•1.9

T=216.6

(Round up because tiles are sold as whole units)

Total tiles=217
