Find the volume of the sphere rounded to the nearest hundredth

Step-by-step explanation:

The volume for a sphere is

. Our radius is 21 inches, so

and

. Multiplying straight across the top, using the fact that 3.14 is pi:

and divide to get that

V = 38772.72 in^3

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
