What is the answer for both questions.

Step-by-step explanation:

The equation has the form Y=a+bX, where Y is the dependent variable (that's the variable that goes on the Y axis), X is the independent variable(i.e it is plotted on the X axis), b is the slope of the line and a is the y-intercept. ( I might be wrong, first time answering a question that I don't know anything about. I looked it up on google.)

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 !
