The average rate of change (ARC) of the function y = f(x) between xy and x2 is f(x2) - f(xi)
ARC =
X2-X
Use appropriate substitution(s) to show that the ARC formula comes from a familiar slope formula.

hi, i am not sure about this one but i think its d,

hope this !

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 !
