Question

The radius r and height h of a right circular cone are both increasing at a constant rate of 2 cm/h. At what rate in centimeters cubed per hour is the volume V of the cone increasing when r = 6cm and h = 15cm? (The volume V of a right circular cone of height h and radius r is V = 1πr2h.)

Answer 1

Answer:

94.2

Step-by-step explanation:

i honestly dont know if this answer is right but i am currently takeing classes in math about Geometry. We was learning about Word problems, that had to do with volume, Area, and perimeter, and learned what radius is, etc..

• So i thought you take the formula it gives you and use. Since Pie means 3.14 you use that in the formula. V= 1×3.14×2×15 = 94.2
• you would multiply everything together because every number is close together.
• the height is 15 cm, thats how you get 15 at the end.
• next step is to solve the equation in your calculator. and it gives you that number. = 94.2
