Answer:
200.96 ft²
Step-by-step explanation:
The question is on surface area of a closed cylinder
Formulae= SA=2 ×pi× r² + 2×pi×r×h
Where pi=3.14
SA= 2×3.14×2² + 2×3.14×2×14
SA=25.12+175.84
SA=200.96 ft²
Answer:
k = 6x/(w + 1)
Step-by-step explanation:
6x - k = wk
6x = wk + k
k(w+1) = 6x
k = 6x/(w + 1)

Answer:
10
Step-by-step explanation:
8+5+15+12+10= 50 / 5 = 10
First we need to factor the left side. Since it is a perfect square (as is the process with completing the square, we know we can take half of the middle number along with x to be in the two parenthesis.
(x - 4)(x - 4) = 25
Now we simplify to show it as a square.
(x - 4)^2 = 25
Next we take the square root of both sides
x - 4 = +/- 5
Note that we have plus or minus 5. This is because either square would give us positive 25. Now we add 4 to both sides
x = 4 +/- 5
4 + 5 = 9
4 - 5 = -1
