The radius of the completed cone is

... 18×(300°/360°) = 15

The height of the completed cone is found from the Pythagorean theorem:

... 15² + h² = 18²

... h = √99 = 3√11

The volume is given by

... V = (1/3)πr²·h = (1/3)π·15²·3√11

Dividing this value by π gives 225√11 cubic units.

Find the surface area
Natasha_Volkova [10]
First, you need to find the area of the rectangle. As you already know, the formula for area is length times width. So, you would need to do 7 times 6, which is 42. Now, the triangle is a little more complicated. the height is about 2 and the base is 6. 6 times 2 is 12, but if you remember the area of a triangle, it's B times H divided by 2, so 12 divided by 2 is 6, so 42 plus 6 is 48. I THINK that is the surface area :)

Which of the following correctly completes the square for the equation below? x^2-9x=0
PolarNik [594]
The answer to this question is choice B. To complete the square, we take the coefficient on the x term, halve it, and then square it. This results in -9/2, and then 81/4. This value of 81/4 is added to both sides, allowing for factorization of the lefthand side of the equation.
