Given a(2,1), b(3,3), and scale factor: 4, graph the image and pre-image under the given dilation. label the endpoints.

  see below

Step-by-step explanation:

Each image coordinate is 4 times the corresponding pre-image coordinate.

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 !
