Step-by-step explanation:
Volume of cylinder = πr²h
Volume = π (12)² × 17
= 2448 π units³
Thus the answer is (d)
Answer:
Step-by-step explanation:
-3i √(-40) = -3i √40i² ...(i² = - 1)
= -3i √40 i
-3i √(-40) = 3√40
62,810 rounded up is 60,00
Let u = x², then we would have u² + 5u - 6 = 0
From here, we can factor it and get us (u-1)(u+6) = 0
So our solution for u is u = -6 or 1.
Now substitute u back to x².
x² = -6 or 1
x = ±√(-6) or ±√1
Since ±√(-6) is not real number, we ignore it.
Which leave us x = ±√1 = <span>±1
So our real solution is x = -1 or 1.</span>
