Answer 6

Ket-kat is here, go Ket-Kat :D

Answer 7

Your answer will be: 150.8

Answer 8

or 150.72 without rounding :D

Answer 9

@Ket-kat You made a little mistake in your formula, 2pi*r is the circonference, the area is pi *r^2

Answer 10

It should be 3.14 * 4^2 * 6

Answer 11

Than, medals for you both i really needed this wanna help me with the last 2 lols

Answer 12

How? That is the surface area equation?

Answer 13

Oh yeah, nvm, I misread the question :s

Answer 14

301.44 isn't even an answer...

Answer 15

That's because you forgot to add the area of the bases :)

Answer 16

No, I'm pretty sure I used the right equation lol. Anyway, there is your answer <3

Answer 17

thanx, there are two more questions though, will you two stay

Answer 18

Yes

Answer 20

The answer should be 251.2
2*3.14*4+(3.14 * 4^2)*2 = 251.2

Answer 21

Find the surface area of a cone with diamter of 13 and a slant height of 5
234.72
433.28
198.75
734.76

Answer 22

The surface area for a cone's formula is pi * r * s + pi * r^2

Answer 23

pi(r)(s) + pi r^2

Answer 24

Radius = 13/2 = 6.5
pi * 6.5 * 5 + pi * 6.5^2 = 234.715

Answer 25

Oh, Zepp is right
