Step-by-step explanation:
V=pir2h
First term = 5
Second term = 5 x 5rn = 25rn
Third term = 25rn x 5rn =

Fourth term =

x 5rn =
Answer:
x = - 6
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use (9, 36), that is x = 9, y = 36
36 = 9k ( divide both sides by 9 )
4 = k
y = 4x ← equation of variation
Using (x, - 24 ), that is find x when y = - 24
- 24 = 4x ( divide both sides by 4 )
x = - 6
Answer:
4 + 6√(3)
Step-by-step explanation:
Two right parentheses seem to be missing here. I think you meant:
(-1 - 3 √(3) ) × (-1 - 3 √(3) )
and this is the square of a binomial. The resulting square is:
1 + 6√3 + 3, or 4 + 6√(3)
