10 points! Please help I dont understand :( (No scams/links please)
TRUE/FALSE
1. If a subset of R is bounded above, it has a maximum element.
2. If a subset of Q is bounded above, it has a least upper bound in Q,

Z(integer)

Step-by-step explanation:

N is subset of W

W is subset of Z

Z is subset of Q

Q and Q* are subset of R

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
