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

What is the surface area of the cone?

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.

You and a friend go to Tacos Galore for lunch. You order three soft tacos and five burritos and your total bill is $17.75. Your friend orders four soft tacos and two burritos and paid $12.00.

Answers

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

Find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis.

y = 3 − 3x^2, y = 0

Answers

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]

4/3 (3x-12)=2x+8 what is x

Answers

The answer is, X = 12.

hope it helps.

Answer:

x = 12

Step-by-step explanation:

simlify 4/3 * (3x-12)

4x - 16 = 2x + 8

combine like terms, so subtract 2x by 4x

2x - 16= 8

then finish combining like terms, so 16 plus 8

2x = 24

divide 24 by 2

x = 12

y = 1/6 × 3

y = 0.5

Answer:

-1/2 and -0.5

Explanation :

Hey! Ok so you will plug in all the value in the y to find out if it equals to 1/6.

y ÷ -3 = 1/6

0.5 ÷ -3 = 1/6

-1/6 = 1/6 ---> NO

y ÷ -3 = 1/6

-1/2 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-0.5 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-18 ÷ -3 = 1/6

6 = 1/6 ---> NO
