a beach ball has a volume of 270 cubic inches waht is the radius of the ball in inches?

Question

whats the anwser how do you solve it

Answer 1

Volume of a sphere is 4/3 r^3 pi. So 270 = 4/3 r^3 pi.
202.5 = r^3 pi
64.5 = r^3
r = 4

Answer 2

Volume for a sphere formula

v = 4/3 π r³

270 = 4/3 (3.141592654)r³

3(270) = 3(4/3)(3.141592654)r³

810 = 4(3.141592654)r³

810 = 12.56637061r³

810 / 12.56637061 = 12.56637061r³/12.56637061

810 / 1.56637061 = r³

64.45775195 = r³

³√64.45775195 = ³√r

4.1660110001 = r

The radius is 4.2 inches rounded to one decimal place.
