Answer:

To find the surface area of a cone, you need to calculate the cone’s base and the lateral surface area.

Since the base of a cone is a circle, then the base area (B) of a cone is given as:

Base area of a cone, B = πr²

Where r = the base radius of the cone

Find the equation of the sphere in standard form centered at (−6,10,5) with radius 5.

Dovator [93]

Answer:

The equation of the sphere in standard form is

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$

Step-by-step explanation:

<u>Step 1</u>:-

The equation of the sphere having center and radius is

$(x-h)^{2} +(y-k)^{2} +(z-l)^{2} = r^{2}$

Given centered of the sphere is (-6,10,5) and radius r=5

$(x-(-6))^{2} +(y-10)^{2} +(z-5)^{2} = 5^{2}$

on simplification,we get

$using (a+b)^{2} =a^{2} +2 a b+b^{2}$

$using (a-b)^{2} =a^{2} -2 a b+b^{2}$

simplify , we get

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$

The slope for 5 and 2

Yuri [45]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

As we know, slope (m) is equal to tan θ for a straight line :

$\qquad \tt\dashrightarrow \: m = \tan( \theta)$

$\qquad \tt\dashrightarrow \: m = \dfrac{5}{2}$

So, we can say that it's a positive constant slope
