What is the surface area of a dome ( 1/2 sphere) with a radius of 12 meters?<br> A.

Step2247 [10]

Answer:

$Area = 1357.344m^2$

Step-by-step explanation:

Given

Shape: dome

$r = 12$

Required

The surface area

This is calculated as:

$Area = 3\pi r^2$

So, we have:

$Area = 3*3.142* 12^2$

$Area = 1357.344m^2$

Solve the equation for all values of x: (x+1)^2=-49

Kazeer [188]

Answer:

Values for x = -1 + 7i and -1 - 7i

Step-by-step explanation:

we have an equation,

(x+1)^2 = -49

We need to solve this equation for all values of x:

(x+1)^2 = - 49

Taking square root both sides

√((x +1)^2) = √-49

x + 1 = ± 7i

Subtract both sides by 1

x = -1 ± 7i

Hence we get two values for x = -1 + 7i and -1 - 7i

Write an equation in point-slope form of the line that passes through the points

Aleksandr-060686 [28]

Hello!

Step-by-step explanation:

Slope: $\frac{Y^2-Y^1}{X^2-X^1}=\frac{rise}{run}$

$\frac{(-2)-(-4)=-2+4=2}{3-2=1}=\frac{2}{1}=2$

<u><em>Answer: 2</em></u>

<u><em>Slope is 2.</em></u>

Hope this helps!

Thanks!
