0.766d = - 0.247d + 0.0233d^2 Solve for d

Step-by-step explanation:

We begin by adding to both sides of the equation.

Next, we can divide both sides of the equation by .

Finally, we divide both sides by , giving us our

Keep in mind, this answer is approximated- if you need more than four decimal places, here are a few more:

i can answer this question sweetie!

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 !
