A cylinder with a height of 12 cm is inscribed in a sphere with a radius of 10 cm. Find the lateral area of the cylinder. Answer
zalisa [80]

Answer:

256π

Step-by-step explanation:

Given that:

The height of the cylinder: 12 cm

The radius of the sphere : 10

Let r is the radius of the cylinder, use Pytagon

10² = r² + 6²

<=> r²  = 10² - 6²  = 64

<=> r = 8

Hence,  the lateral area of the cylinder

L= 2πrh

= 2π8*16

= 256π

Find each function value.
Levart [38]

Put the values of x to the equations of the functions:

1. f(9) → x = 9; f(x) = -3x + 10

f(9) = -3(9) + 10 = -27 + 10 = -17

2. f(-2) → x = -2; f(x) = 4x - 1

f(-2) = 4(-2) - 1 = -8 - 1 = -9

3. f(-5) → x = -5; f(x) = -2x + 8

f(-5) = -2(-5) + 8 = 10 + 8 = 18

Solve the equation -4x + 7 y equals 20. Y=3x+15
satela [25.4K]

Substitue what y equals for y and solve.

-4x+7(3x+15)=20 \\-4x+27x+105=20 \\23x=-85 \\x=-\boxed{\frac{85}{23}}

Hope this helps.

Write the equation of the line in point slope form that passes through (-1, -2) and ( 1, 4).
Musya8 [376]

Answer:

y+2= 3(x+1)

Step-by-step explanation:

First you need to find slope by using y2-y1/x2-x1

you should get 3 for your slope(m)

Them you chose any point iḿ using (-1, -2)

The formula for point slope form is...

y-y1=m(x-x1)

plug those numbers in and you get

y + 2 = 3(x + 1)
