Answer:
V = V = 175 pi units^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V =pi ( 5)^2 ( 7)
V = 175 pi units^3
If it is 3kg, it will be:
40mins x 3 = 120mins
Add the extra 20 mins, it will be 140 mins. This equates to two hours and 20 minutes.
Answer:
1/4
Step-by-step explanation:
<span>3a4-2a2+5a-10)-(2a4+4a2+5a-2)
remove first set of parentheses:
apply "-" sign to second parentheses (distributive prop):
the - of a - becomes a + :
combine like terms:
Factor out the variables that are alike:
{(1)a^4 + (-6)a^2 + 0a + (-8)}}}
0a is just 0, makea the "a" term go away:
can try to factor as squares, but it doesn't work out:
8 = (-4) x (+2) product factors cannot add to make 6. </span>
