PLEASE HELP NO Which expression can be used to find the volume of the sphere?

A sphere with diameter 10 inches.
V = four-thirds pi r squared = Four-thirds (3.14) (5) squared
V = four-thirds pi r cubed = Four-thirds (3.14) (5) cubed
V = four-thirds pi r cubed = Four-thirds (3.14) (10) cubed
V = four-thirds pi r squared = Four-thirds (3.14) (10) squared

The answer is the second one

Step-by-step explanation:

The formula to find the volume of a sphere is 4/3πr^3.

Four-thirds (3.14) (5) cubed is right because the r represents radius and the radius is half of the diameter which is 10 so it's 5

B

Step-by-step explanation:

Because i just pack a punched my ray gun

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
