the equation for volume of a sphere is (4/3)(pi)(r^3)
plug 34 in,
(4/3)(pi)(r^3)=34
divide both sides by 4/3:
pi(r^3)=25.5
divide both sides by pi
r^3=8.116902098
take the cube root:
r=2.009694771
Hope this helps

V = ((4pi)/3) * r^3
34 = ((4pi)/3) * r^3
Multiply both sides by 3
102 = 4pi * r^3
(51/2) = pi * r^3
r^3 = 51/(2pi)
r = 2.00969

V = 4/3(pi)r^3
(v / pi) (3/4) = r^3
(34/3.14) (3.4) = r^3
8.12 = r^3
r = 2.01
Test answer
v = (4/3) (pi) (r^3)
v = (4/3) (3.14) (2.01 * 2.01 * 2.01)
v = 33.998 appox 34
