Asphere has a diameter of 10 in. what is the volume of the sphere?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Divide. –4.2 ÷ 6 = a –0.7 b 0.7 c –7 d 7 me
