The cone and cylinder below have equal surface area

The Cone And Cylinder Below Have Equal Surface Area

Answers

Answer 1

Answer:

Option B, False

Step-by-step explanation:

Step 1:  Get the surface area formulas for both shapes

Surface Area Formula for Cone:  [tex]A = \pi * r(r + \sqrt{h^{2} + r^{2}})[/tex]

Surface Area Formula for Cylinder:  [tex]A = 2\pi rh+2\pi r^{2}[/tex]

Step 2:  Plug in the values and solve

Cone:  [tex]A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})[/tex]

Cone:  [tex]A = \pi r^{2} + \pi \sqrt{10}r^{2}[/tex]

Cylinder:  [tex]A = 2\pi r*r+2\pi r^{2}[/tex]

Cylinder:  [tex]A=4 \pi r^{2}[/tex]

Step 3:  Compare

[tex]\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}[/tex]

They are not equal, therefore the answer is False.

Answer:  Option B, False

Complete the statements about the cone.
The height is units.
The radius is units.
The volume is Tot cubic units.
10
6

Answers

Answer:

The answers are:

The height is 6

The radius is 8

The volume is 128 π cubic units.

Step-by-step explanation:

The height is shown in the picture. So the first answer is 6.

To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius

The slant height 10, and the height is 6. So you plug those into the equation and solve.

[tex]\sqrt{10^{2}-6^{2} }[/tex] =

[tex]\sqrt{100-36}[/tex] =

[tex]\sqrt{64}[/tex] = 8

So the radius is 8.

Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.

[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =

[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =

[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units

I hoped this helped you. I would love brainiest.

The statements about the cone is that,

The height is 6 units, the radius is 8 units and the volume is 128π cubic units.

What is Volume?

Volume of a three dimensional shape is the space occupied by the shape.

Given a cone.

We have to find the complete the statements related to the cone.

From the figure,

height of the cone = 6 units

Using the Pythagoras theorem,

Radius of the cone = √(10² - 6²) = 8 units

Volume of the cone = 1/3 π r² h

                                 = 1/3 π × 8² × 6

                                 = 128π cubic units

Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.

the side lengths.

Answers

Just trying to win the CONTEST BUT GOOOOD LUCK

Answer:

56 units, 84 units, 56 units, 140 units

Step-by-step explanation:

Since you have the ratios, you can multiply each by x, because you do not know the actual values.

2x+3x+2x+5x=336

12x=336

÷12  ÷12

x=28

Then, plug in the values of x.

So 2*28= 56

3*28=84

2*28=56

5*28=140

Applying the secant-tangent segment theorem, the equation that will result using the figure given is: C. 10(a + 10) = 12².

What is the Secant-tangent Segment Theorem?

The secant-tangent segment theorem states that if a tangent and a secant intersect at a point outside a circle, then the square of the measure of the products of the secant segment and its external secant segment equals the square of the measure of the tangent segment.

Thus, using the figure given, the equation that results from applying the secant-tangent segment theorem would be: C. 10(a + 10) = 12²

Which of the following equations represents a line that is parallel to the line 3x - 2y = 12
and passes through the point (7, 10)?

Answers

Answer:

Step-by-step explanation:

12=3x-2y

2y+12=3x

2y=3x-12

y=(3x-12)/2

y=mx+b

To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be

y=1.5x+b, using point (7,10) we can solve for the y intercept or b

10=1.5(7)+b

10=10.5+b

b=-0.5 so our line is

y=1.5x-0.5

What is X...

What is Y....

Answers

Answer:

x = 110

y = 40

Step-by-step explanation:

m∡5 = 30° because it forms a linear pair with ∡6, which is 150°

x + y = 150  (angles 4 and 6 are alternate-interior and are congruent)

angles 3 and 6 are same-side interior and are supplementary

therefore:  x -2y = 180-150

if x + y = 150 we can say that x = 150 - y

we can plug '150-y' for 'x' in x - 2y = 30

150-y - 2y = 30

-3y = -120

y = 40

x = 110

Mya and her three friends bought 7 1/5 pounds of cherry sours at 1.30 per pound. If the cost of cherry sours id divided evenly among the 4 friends, how much will each person pay

Answers

Answer: Each person will pay $2.34.

Step-by-step explanation:

Given: Cost of one pound of cherries = $1.30

Cost of [tex]7\dfrac15[/tex] pounds of cherries  = [tex]7\dfrac15\times 1.30[/tex]

[tex]=\dfrac{36}{5}\times1.30[/tex]

= $9.36

Each person will pay = (Cost of [tex]7\dfrac15[/tex] pounds ) ÷ 4

[tex]=9.36\div4[/tex]

=$2.34

Hence, Each person will pay $2.34.
