The object below was made by placing a cone on top of a cylinder. The base of the cone is congruent to the base of the cylinder.

Answer:

Part 1) The volume of the object is $32\pi\ cm^{3}$ or $100.48\ cm^{3}$

Part 2) see the procedure

Step-by-step explanation:

Part 1) What is the volume, in cubic centimeters, of the object?

we know that

The volume of the object is equal to the volume of the cylinder plus the volume of the cone

Find the volume of the cone

The volume of the cone is equal to

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

we have

$r=4/2=2\ cm$ -----> the radius is half the diameter

$h=3\ cm$

substitute the values

$V=\frac{1}{3}\pi (2^{2})(3)=4\pi\ cm^{3}$

Find the volume of the cylinder

The volume of the cylinder is equal to

$V=\pi r^{2} h$

we have

$r=4/2=2\ cm$ -----> the radius is half the diameter

$h=(10-3)=7\ cm$

substitute the values

$V=\pi (2^{2})(7)=28\pi\ cm^{3}$

Part 2) Then explain how you found the volume of the total shape

The volume of the total shape is equal to the volume of the cylinder plus the volume of the cone

$4\pi\ cm^{3}+28\pi\ cm^{3}=32\pi\ cm^{3}$ ------> exact value

Find the approximate value of the volume

assume $\pi=3.14$

$32(3.14)=100.48\ cm^{3}$

Answers for the 2 boxes please:)

Answer:

(6, - 9 )

Step-by-step explanation:

Given the 2 equations

6x + 2y = 18 → (1)

- 4x - 2y = - 6 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

2x + 0 = 12

2x = 12 ( divide both sides by 2 )

x = 6

Substitute x = 6 into either of the 2 equationsand solve for y

Substituting into (1)

6(6) + 2y = 18

36 + 2y = 18 ( subtract 36 from both sides )

2y = - 18 ( divide both sides by 2 )

y = - 9

solution is (6, - 9 )

Solve for w. w−8=32 a: 4 b:24 c: 40 d: 256

IceJOKER [234]

The answer would be c.
What you would do is add 8 on both sides of the equal sign. After doing this your equation should look like, w= 32+8. When you add 32 and 8 together you would get 40. After doing this your answer should look like w= 40.
Hope this helps! (:
