Formula for volume of cylinder: pi*r^2*h
170 = 3.14*2.5^2*h
170=19,625*h
170/19.625 = h; h = 8.66 inches
First you have to put like terms together:
bf+af+be+ae
Now you factor the first two terms and then the two last terms:
f(b+a)+e(b+a)
Now you factor even further. By putting what is in parentheses by what is outside the parentheses:
(b+a)(f+e)
What you got is correct as mine is too. I hope this formula helps for future problems:
ax+bx+ac+bc=x(a+b)+c(a+b)
=(a+b)(x+c)
Answer:
Right
Step-by-step explanation:
One of the angles is 90 degrees.
I would guess 4 hours in that case
