A family purchases a light sphere to be used out on their patio. The diameter of the sphere is 20 in. What is the volume of the light sphere? Use 3.14 for pi.

The volume of the light sphere is 2355in³

Step-by-step explanation:

We know that the formula to calculate the volume of a sphere is

 v = 3/4 * π * r³

we know that the diameter is 20in but we need to know the radius, the radius is half the diameter

r = 1/2 * 20in

r = 10 in

π = 3.14

we replace the values and calculate the volume of a sphere

v = 3/4 * 3.14 * (10in)³

v = 3/4 * 3.14 * (1000in³)

v = 2355in³

The volume of the light sphere is 2355in³

what i would say the best answer is a. 40.5

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
