A party supply store needs to know how much helium to put inside of balloons. Determine the volume of a spherically shaped balloon with a radius of 10.5 cm.

4849 cm^3

Step-by-step explanation:

V = (4/3)(pi)r^3

V = (4/3)(3.14159)(10.5 cm)^3

V = 4849 cm^3

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
