Answer 2

The slant height of the cone is 5.6km, the total surface area is 50.4πkm, the lateral surface area is 16.8π km.

What is a cone?

A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreases to a certain point.

The volume of a cone is (1/3)πr²h.

The total surface area of a cone is πr(r + l).

The curved surface area is πrl.

In the given question radius of the cone is (6/2) km = 3 km.

The slant height of the cone is 5.6 km.

The total surface area of the cone is = π×3(3 + 5.6) km.

= 3π(16.8) km.

= 50.4π km.

lateral surface area is = π×3×5.6 km.

= 16.8π km.

Find the surface area of the regular pyramid. 14mm and height is 11.

Answers

Answer:

504

Step-by-step explanation:

TSA (total surface area) = 1/2(p)(l) + B

p (perimeter) = 4(14) = 56

l (slant length) = 11

B (area of vase) = 14(14) = 196

TSA = 1/2 (56) (11) + 196

= 28(11) + 196

= 308 + 196

= 504

Granny needs to paint a Loge made using two right triangles the dimensions Of the loge are shown below what is the difference between the area of the large triangle in the area of a small triangle

Answers

Answer:

The difference is

Step-by-step explanation:

Given

Large triangle

[tex]Base = 5cm; Height=9cm[/tex]

Small triangle

[tex]Base = 2cm; Height=6cm[/tex]

See attachment for logo

Required

The difference in their areas

Area is calculated as:

[tex]Area = 0.5 * base * height[/tex]

For the large triangle

[tex]Area = 0.5 * 5cm * 9cm[/tex]

[tex]Area = 22.5cm^2[/tex]

For the small triangle

[tex]Area = 0.5 * 2cm * 6cm[/tex]

[tex]Area = 6cm^2[/tex]

The difference (d) is calculated as:

[tex]d = 22.5cm^2 - 6cm^2[/tex]

[tex]d = 16.5cm^2[/tex]

Answer: Figure A to Figure B is a scale factor of 0.5

Step-by-step explanation:

It's not too hard to figure out scale factor, since the two shapes are the same aside from their scale. Notice how Figure A is 4 units tall, and that Figure Bis 2 units tall. From one figure to another, use the equation Figure B/Figure A to find the scale factor. Although you won't really need to memorize all this, you can count the amount of units on your fingers and figure it out from there.

2. The volume of a cylinder is 95 cubic centimeters. Which equation
can be used to find h, the height of the cylinderę Circle the correct
answer.

Answers

Given:

The volume of a cylinder is 95 cubic centimetres.

To find:

The equation that can be used to find h, the height of the cylinder.

Solution:

We know that, the volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

We know that the base of the cylinder is a circle and the area of the circle is [tex]\pi r^2[/tex]. So, the base area of the cylinder is [tex]B=\pi r^2[/tex].

Now, volume of the cylinder is

[tex]V=Bh[/tex]

The volume of a cylinder is 95 cubic centimetres.

[tex]95=Bh[/tex]

[tex]\dfrac{95}{B}=h[/tex]

[tex]h=\dfrac{95}{B}[/tex]

Where B is the base area of the cylinder.

Therefore, the correct option is G.

The sum of the 1st nth term gp is 127.the sum of the reciprocal is 127/64,if the 1st term is 1.find n and the common ratio

Answers

Answer:

Ratio (r) = 2

n = 7

Step-by-step explanation:

The formula for the sum of the nth term of a G.P is given as:

Sn = a(1-r^n)/(1-r)

Where n = Number of terms

r = Common ratio

The sum of the 1st nth term gp is 127.

Hence:

127 = 1(1-r^n)/(1-r)

The sum of the reciprocal is 127/64

The formula is inverted , hence:

Sn = 1/a(1-r^n)/(1-r)

127/64 = r^(1-n)(1-r^n)/(1-r)

Hence:

1/64 = r^(1-n)

r^(n-1) = 64

r^(n-1) = 2⁶

Hence:

r = 2

Solving for n

n - 1 = 6

n = 6 + 1

n = 7

Therefore:

r = 2

n = 7

Solve this system using substitution: y=5x and 7x-3y=32

Answers

Solve equation [2] for the variable y

[2] 2y = -5x + 1

[2] y = -5x/2 + 1/2

// Plug this in for variable y in equation [1]

[1] 7x - 3•(-5x/2+1/2) = -5

[1] 29x/2 = -7/2

[1] 29x = -7

// Solve equation [1] for the variable x

[1] 29x = - 7

[1] x = - 7/29

// By now we know this much :

x = -7/29

y = -5x/2+1/2

// Use the x value to solve for y

y = -(5/2)(-7/29)+1/2 = 32/29

Solution :

{x,y} = {-7/29,32/29}
