V = (4/3)*pi*r^3
V = volume
pi = about 3.14
r = 1.3
V = (4/3)*3.14*1.3^3
V = 9.20 units cubed.

Volume formula for a sphere
V = 4/3 Ï r³
1.3³ = 1.3 x 1.3 x 1.3 = 2.197
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
v =4/3(3.141592654)(2.197)
x=12.56637061/3(2.197)
multiplying 4 times 3,141592654= 12.56637061
v = 4.188790205(2.197)
Dividing 12.56637061 by 3
v = 9.20277208
multiplying 4.188790205 times 2.197 = 9.20277208
v = 9.2 rounded to one decimal place
The answer is 9.2

V = (4pi/3)r^3
V = (4/3) * (1.3)^2 * pi
V = (4/3) * 1.69 * pi
V = about 7.079

I agree with PolloLoco, with this clarification
radius is r and r ^3 means r *r *r or r cubed.
