Step-by-step explanation:

Step-by-step explanation:

1.

(2x-11)° = 105° (vertical angles)

2x - 11 = 105

2x = 105 + 11

2x = 116

x = 116/2

x = 58

2.

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 !
