Answer:
{- 11, - 1 }
Step-by-step explanation:
Since the coefficient of the x² term is 1 , to complete the square
add (half the coefficient of the x-term )² to both sides
x² + 2(6)x + 36 = - 11 + 36 ← complete the square on the left side
(x + 6)² = 25 ( take the square root of both sides
= ±
x + 6 = ± 5 ( subtract 6 from both sides )
x = - 6 ± 5
x = - 6 + 5 = - 1 or x = - 6 - 5 = - 11
Answer:
Option A -
Step-by-step explanation:
Given: The volume of a cylinder =
Let us substitute the volume of cylinder in the formula.
The formula for volume of a cone is (1)
The formula for volume of a cylinder is (2)
Substituting in equation (2), we get,
Given that the cone has the same radius and height of that of the cylinder, let us substitute in equation (1)
Thus, the volume of a cone with the same radius and height of a cylinder is .
