Meh need answer plez and FAST~

The surface area of the cone is 16π square units.

The surface area of the cone is given by;

⇒ Area = πrl + πr²

Here, We have;

A right cone has a slant height of 6 and a radius of 2.

Substitute all the values in the formula

⇒ Area = πrl + πr²

⇒ Area = π x 2 x 6 + π x 2²

⇒ Area = 16π

Hence, The surface area of the cone is 16π square units.

I really need point

Answer: [tex]9.6\pi[/tex]

Step-by-step explanation:

Given

Curve is [tex]y=3-3x^2[/tex]

boundary is y=0 i.e.

[tex]\Rightarrow 0=3-3x^2\\\Rightarrow x^2=1\\\Rightarrow x=\pm 1[/tex]

The volume of solid generated when rotated about the x-axis is

[tex]\Rightarrow V=\int_a^b\pi y^2dx[/tex]

Putting values we get

[tex]\Rightarrow V=\int_{-1}^{1}\pi (3-3x^2)^2dx\\\\\Rightarrow V=\int_{-1}^{1}\pi(9+9x^4-18x^2)dx\\\\\Rightarrow V=\pi \left [ \frac{9x^5}{5} - 6 x^3 + 9 x\right ]_{-1}^{1}\\\\\Rightarrow V=9.6\pi[/tex]

Answer:

x - 8 = 0

Step-by-step explanation:

Since, the cube root of a number is 2.

Let the number be x.

Therefore,

[tex] \sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0[/tex]

Answer:

its gonna be 3ft and 10 inch

Answer:

Step-by-step explanation:

let tacos be x and burritos be y

so, your 1st eqn. is 3x + 5y = 17.75

2nd eqn. is 4x+ 2y = 12

Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5

So: 6x+10y=35.5

-20x-10y=-60

=-14x=-24.5

x=24.5/14 = 1.75

Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75

y = 2.5

answer: 37.7cm^2

area of 2cm = 12.57cm^2

area of 4cm = 50.27cm^2

50.27 - 12.57 = 37.7

Answer:

3.3x =15

x=15÷3.3

x= 4.5454545454

Answer:

Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor).

Step-by-step explanation:

2 cot²(t ) sin(t ) - cot²(t ) = 0

cot²(t ) (2 sin(t ) - 1) = 0

cot²(t ) = 0   or   2 sin(t ) - 1 = 0

cot(t ) = 0   or   sin(t ) = 1/2

cos(t ) / sin(t ) = 0   or   sin(t ) = 1/2

cos(t ) = 0   or   sin(t ) = 1/2

[t = cos⁻¹(0) + 2nπ   or   t = cos⁻¹(0) - π + 2nπ]

  or   [t = sin⁻¹(1/2) + 2nπ   or   t = π - sin⁻¹(1/2) + 2nπ]

(where n is any integer)

t = π/2 + 2nπ   or   t = -π/2 + 2nπ   or   t = π/6 + 2nπ   or   t = 5π/6 + 2nπ

Note that the first two families of solutions overlap and can be condensed, so that

t = π/2 + nπ   or   t = π/6 + 2nπ   or   t = 5π/6 + 2nπ

Answer:

I think 235.5 mm cubed

Step-by-step explanation:

The formula for the volume of a cone is V=1/3hπr².

1/3 x 9 x π x 5² =

1/3 x 9π x 25 =

1/3 x 225π =

75π

let's say π=3.14

75 x 3.14 = 235.5

Answer:

Talia needs to factor -1 out of one of the two binomials

Step-by-step explanation:

She could take:

3x(5x - 1) + 4(-5x + 1)

and rewrite it as:

3x(5x - 1) - 4(5x - 1)

= (3x - 4)(5x - 1)

Step-by-step explanation:

Answer:

5 ft

Step-by-step explanation:

area = L * W * H

35    =  L * W

Volume = (L *W) * H

since we have already found that L * W is already 35

175 = 35 * H

Divide by 35  on both sides to get H

175/35 = 5

answer = 5 ft

Approximately $242,000

Answer:

(0,-9), x = 0, (-3,0), (3,0), domain, -9

Step-by-step explanation:

Complete the square and you can read everything off the equation,

y  = x^2 - 9

= (x - 0)^2 - 9

Vertex : (0,-9)

Axis of symmetry: x = 0

x-intercepts:  x^2 = 9 -> x = ±3

Left x-intercept: (-3,0)

right x-intercept: (3,0)

Since the function is well-defined for any x-values,

we can say that its domain is the set of all real numbers.

Since the minimum point of the graph is (0,-9),

The range will be greater than or equal to -9.

Answer:

4

Step-by-step explanation:

Making this problem into a proportion we get:

6/$15 = x/$10

Cross multiply 10 and 6, we get 60. Now divide that by 15, you get 4.
