What is the surface area of a cone that has a radius of 8 feet and a slant height of 12 feet? (Use 3.14 for π.)

kodGreya [7K]

Answer:

Surface area of cone is $502.4\ ft^2$

Step-by-step explanation:

Given:

radius of a cone (r) = 8 feet

slant height of cone (l) = 12 feet

We need to find the surface area of cone.

Total surface area of cone = Area of circle $+$ Area of curved surface

Now we know that,

Area of circle = $\pi r^2$

Area of curved surface = $\pi rl$

Hence Total surface area of cone = $\pi r^2+\pi rl=\pi r(r+l) = 3.14 \times 8 (8+12)=3.14\times8\times20= 502.4 \ ft^2$

Surface area of cone is $502.4\ ft^2$ .

3.) 32500, 1.5, 32500 makes sense

4.) [0,+ ∞ ]

Step-by-step explanation:

1.) r(-3) = 2500 - 3*5000=10000

2.) f(3) = 25000 + 3*5000 = 40000

3.) f(1.5) = 25000 +1.5*5000= 325000

What is the first term of the expression? −6xyz + 9xy + 12x + 18y TIA!

tatyana61 [14]

For this case we have that by definition:

The terms of a polynomial expression are those that are composed of coefficients and variables separated by signs of addition and subtraction.

We then have the following expression:

$-6xyz + 9xy + 12x + 18y$

According to the definition, we can conclude that the first term is given by:

$-6xyz$

Answer:

The first term of the expression is:

$-6xyz$
