Nope

Answer 4

give me a second @AZ

Answer 5

we need to know how much surface area the paint will cover but here is how to find that surface area
Step-by-step explanation:
1 fence post has a surface area of pi*diameter* height
pi * 1 * 5 =15.707963
10* fence post =157.07963 sq ft

Answer 6

Are u sure

Answer 7

That's wrong

Answer 8

I remember answering this exact question a few weeks ago too

Surface area of cylinder = \( 2\pi rh+2\pi r^2 \)

So plug in r = 0.5
diameter is 1 so the radius is half of that

and height is 7

so what is the surface area of 1 wooden fencepost?

Answer 9

259.05 sq

Answer 10

That would be your final answer, yes

you multiply the surface area by 11 so you can find how much surface area you're painting for 11 fenceposts

However, keep in mind that the units should be square feet!
