If m=5 and n=3, find the value of mn.

15

Step-by-step explanation:you multiply m=5 to n=3 so what is 5 times 3? so 5 times 3 = 15

 refer to that question In which what i found from that question Is this should be the answer What is asked in the problem is simply the volume of the solid rubber ball. The volume of sphere given the diameter may be calculated by,                                 V = πd^3 / 6
Substituting the given value of diameter,                                 V = (π x 3³) / 6 = 9π/2 or 14.14
Thus, one needs approximately 14.14 in³ of material.
