Answer:
Solution given:
radius [r]=2cm
height [h]=8cm
total surface area of cylinder=?
we have
total surface area of cylinder=2πr²+2πrh
- 2πr(r+h)
- 2π*2(2+8)
- 40π or 125.66cm²
<u>total surface area of cylinder</u><u>40π or 125.66cm²</u><u>.</u>
First find the volume of the box:
V=2*2.2*2.5=11 cm^3
Then find the desity given by grams divided by volume:
density=25.6 g/ 11 cm^3 = 2.327 g/cm^3
Round to the nearest tenth, so 2.3 g/cm^3.
I hope that helped.
Answer:
You can probably go pro at skating by just practicing a ton and learning new skills and tricks that separates you from other skaters. Its not very hard to be a "pro", its hard to make money off of skating because of the lack of audience it has. Also, I assume your baseball cap is uncomfortable because of the material or your hair.
Hope that helps
