To the nearest tenth of a cubic inch, how much volume is added to a spherical ballon whose radius grows from 10 to 20 inches long?
a) 8245.7 in^3
b) 17367.6 in^3
c) 29321.5 in^3
d) 41225.4 in^3

C) 29321.5 in^3

Step-by-step explanation:

We find the volumes of the two spheres and then we find the difference.

radius = 10 inches

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

V = (4/3)(3.14159)(10 in)^3

V = 4188.8 in^3

radius = 20 inches

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

V = (4/3)(3.14159)(20 in)^3

V = 33510.3 in^3

The difference in volumes is:

33510.3 in^3 - 4188.8 in^3 = 29321.5 in^3

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465
