F(x) = 8x + 1
f^-1(x)

f^-1(x) = 1/8x+1 (an inverse power is the reciprocal of the function raised to the indicated value)

y=mx+b is the final answer!   : )

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 !
