Furkat [3]3 years ago

Answer:

Step-by-step explanation:

2 | x + 5.3 | = 4.2

| x + 5.3 | = 4.2 / 2

| x + 5.3 | = 2.1

x + 5.3 = 2.1 x + 5.3 = - 2.1

x = 2.1 - 5.3 x = -2.1 - 5.3

x = - 3.2 x = - 7.4

solution is : x = -3.2 or x = -7.4

Answer:

1135.2 in³

Step-by-step explanation:

The volume of a sphere is given by the formula ...

V = (4/3)πr^3

The difference in volume will be ...

∆V = Vb -Vs = (4/3)π(10^3 -9^3) = (4/3)π(1000 -729) = 4/3π·271 . . . cubic in

∆V ≈ 1135.2 . . . cubic inches

The basketball has a volume that is 1135.2 cubic inches greater.

_____

If you use 3.14 for π, your answer is 1134.6 in^3.
