Calculate the volume of a cylindrical steel bar which is 8 cm long and 3.5 cm in diameter

76.97 cm!!

Step-by-step explanation:

The equation for this would be V=π(d/2)^2h.  So, V= π (pi) (3.5/2)^2 8, so just solve that and you get the answer above!!

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
