Which relation represents a function? 的 {(0,0).(2,3).(2,5),(6,6) {(3.5). (8,4).(10,11).(10,8) {(-2,2).(0,2).(7.2).(11,2) {(13,2), (13,3), (13,4), (13,5)}​

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 !
