Answer:

Surface area of the cone = 360π in²

Step-by-step explanation:

Formula for the surface area of a cone is,

Surface area = πr(r + l)

Here 'r' = radius of the circular base of the cone

l = Lateral height of the cone

Now we substitute the values in the formula from the figure attached,

Surface area = π(10)(10 + 26)

= 360π in²

Therefore, surface area of the cone will be 360π in².

I found 50, making a rule of three where
40__10
x___25

x=10
40+10= 50
( I hope I'm right, but from what I understand this would be the resolution)

Find the solution of the system of equations. – 5 - 6y = -32 4x - 6y = 4

amid [387]

Equation (1)

$-5 - 6y = -32$

Equation (2)

$4x - 6y = 4$

Get y alone in equation (1)

$-5 - 6y = - 32\\-6y = -32 + 5\\-6y = -27\\y = \frac{-27}{-6} = \frac{9}{2}$

Insert y in equation (2)

$4x - 6 \cdot \frac{9}{2} = 4\\4x - 27 = 4\\4x = 4 + 27\\4x = 31\\x = \frac{31}{4}$

Simplify the expression -9+7

xenn [34]

We have

-9 + 7 = -2

You can also rewrite this as

7 - 9 = -2

If it makes you more comfortable.

Hope this helps.
