Ineed to know how to do this an the answer

The third one

Step-by-step explanation:

r=square root of (v/ πh)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

the correct answer is x/3+10≥32

hope this !
