PLEASE HELP!
Find the volume of the sphere in terms of Pi

972*Pi

Step-by-step explanation:

(see attached pic for reference)

the formula for volume of sphere is given by:

V = (4/3)πr³

we are given that r = 9 units,

substituting this into the formula gives us:

V = (4/3)πr³

V = (4/3)π(729)

V = 972π

2p + q = 1

9p + 3q + 3 = 0

q = 1 - 2p

replace q = 1 - 2p into 9p + 3q + 3 = 0

9p + 3(1 - 2p) + 3 = 0

9p + 3 - 6p + 3 = 0

3p + 6 =0

3p = -6

p = -2

q = 1 - 2p

q = 1 -2(-2)

q = 1 + 4

q = 5

(-2 , 5)

there for the answer would be

{(-2, 5)}
