Use the formula:
Radio= r, Height= h
V= 3.14xrx2h
r =25, h=31
V= 3.14 x 25 x 2 (31) =. 4867
V= 4867 cubic inches
Step-by-step explanation:
3 - (7a + 1) =
3 - 7a - 1 =
-7a + 2 <===
we have to firstly apply the distance formula to find the length of sides of the triangle
distance formula = 
So length AB = 
BC= 
AC = 
Now perimeter = AB+BC+AC = 
Plug in calculator
perimeter= 11.4 units
There are many factors, it is all a matter of preference, normally, you want to try to solve for the easiest one to get to
example
if y ou had
(x-3)^2+y=9
you would solve for y becuase it is less tricky
it is all a matter of preference
<span>You must get p by itself, so first subtract B from both sides: SA-B=1/2lp. Then multiply both sides by 2, which cancels out the 1/2: 2SA=lp. Then divide both sides by l: (2SA)/l=p.</span>
