Answer:
4.30 inches
Step-by-step explanation:
Given data
Volume of basket ball= 334cubic inches
We know that the expression for the volume of a sphere is given as
Volume of sphere= 4/3πr^3
334= 4/3πr^3
334=4/3*3.142*r^3
334=4.189*r^3
r^3= 334/4.189
r^3=79.73
cubic root both sides
r= ∛79.73
r=4.30 inches

Answer:
-2, 1, 4.
Step-by-step explanation:
The given equation is
It can be written as a system of equations.
Plot the graph of these equation on a coordinate plane as shown below.
From the graph it is clear that the graph of both curves intersect each other at (-2,4), (1,-5) and (4,40).
The x-coordinates of intersection points are -2,1 and 4. It means, the given equation is true for -2,1 and 4.
Therefore, the zeroes of given equation are -2,1 and 4.
