Which one doesn't belong 50.1 repeating,-50/2,-50.1,and the square root of 50?

sq rt 50 does not belong

Because all the other numbers are rational numbers and that the only recurring number (has a zero and it repeats)

646

Step-by-step explanation:

To solve this, you would need to know the volume of a sphere and volume of a cube.

Volume of a cube is L x W x H

8x8x8 which gives you 512

The volume of a sphere is

(radius which is 8/2=4)  4/3 pi (4)^3=268.08

Because this is half a sphere, simply divide the volume by 2 and you should get 134.04.

512+134.04=646.04

=646 cm cubed
