Hey!! sooo confused? help:))

-4 I think

Step-by-step explanation:

Since it is about the origin and it is moving counterclockwise we first have to connect C to the origin. Once we do, we then make another line to form a right triangle but it has to be to the left since it is COUNTERclockwise, dont forget the many units from the origin to the original point c is about 4. So when we make the line to form the right triangle we have to reach 4 units, and 4 units up to the left is -4.

i need a picture

step-by-step explanation:

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 !
