Answer 2

The answer for the first question is D. Answers to Questions 2-5 that were said by Cheese Block are right.

Answer 3

The correct answer is D. sphere = cylinder + cone.

The volume formula for a sphere is (4/3)πr^3, where r is the radius.
The volume formula for a cylinder is πr^2h, where r is the radius and h is the height.
The volume formula for a cone is (1/3)πr^2h, where r is the radius and h is the height.

Given that the cylinder and cone have the same height (which is twice the radius), we can write the volume formula for the cylinder as πr^2(2r) = 2πr^3, and the volume formula for the cone as (1/3)πr^2(2r) = (2/3)πr^3.

Adding the volume of the cylinder and the cone, we get 2πr^3 + (2/3)πr^3 = (8/3)πr^3.

Comparing this with the volume formula for the sphere (4/3)πr^3, we can see that (8/3)πr^3 = (4/3)πr^3.

Canceling out the common factor of πr^3, we are left with 8/3 = 4/3, which is not true.

Therefore, the correct relationship between the volume formulas for the sphere, cylinder, and cone is sphere = cylinder + cone.
