I GIVE MEDALS AND FAN!


A gardener purchases a ceramic planter, in the shape of a hemisphere, for a small batch of leftover annuals. The volume of a hemisphere is modeled by the function V = πr 3

1. Write a model for the radius as a function of the volume.
2. The label on the planter says that it holds approximately 134 cubic inches of potting soil. What is the radius of the planter, rounded to the nearest inch? Use 3.14 for π

Answer 1

r^3=V/pi r=(V/pi)^1/3

Answer 2

Okay, so that's number 1?

Answer 3

yes

Answer 4

Okay. Can you help me on number 2 also?

Answer 5

Volume is provided in your question 134 in^3
r=(134/pi)^(1/3)

Answer 6

Alright, thanks!

Answer 7

your welcome :)
