1.
and proving it is an odd number is easy -
is even because of the two in the front
is even because of the two in the front
and the remaining makes it odd.
2. volume of sphere =
volume of cylinder = where H is the height.
comparing the two:
1)Expand and simplify
I got ????
If n is a whole number show that this expression must be an odd number. From my previous post would this be the answer: (3n)(76)
2)The radius of a sphere is 3y cm
The radius of a cylinder is 2y cm and the cylinder's height is H cm
The volume of the sphere is equal to the volume of the cylinder
Express the Height (H) of the cylinder in terms of y. Write in the simplest form. No idea how to do this. Please show me a method
