The correct answer to A is true

everything else looks okay to me.. 

I don't know if you are right for the rest since I multiplied and didn't get any of them XD so I'm going to trust you on that. Maybe you should double- check just to be sure though.

Find the lateral area of a cone with radius 6 in. and height 10 in. Round your answer to the nearest tenth. Use 3.14 for pi.
zhenek [66]

Lateral Cone Area = PI * radius * slant height

slant height ^ 2 = 6^2 + 10^2

slant height ^ 2 = 36 + 100

slant height ^ 2 = 136

slant height ^ 2 = 11.6619037897

Lateral Cone Area = PI * 6 * 11.66

Lateral Cone Area = 219.6744

That's my calculation and I used an online calculator which says the same thing. It is NOT one of the choices.

Solve this system using the linear combination method. Show your work.
kipiarov [429]

Answer:

Let's solve for x.

4x+2y=5

Step 1: Add -2y to both sides.

4x+2y+−2y=5+−2y

4x=−2y+5

Step 2: Divide both sides by 4.

4x

=

−2y+5

Let's solve for x.

−4x−5y=7

Step 1: Add 5y to both sides.

−4x−5y+5y=7+5y

−4x=5y+7

Step 2: Divide both sides by -4.

−4x
