Find the volume of a right circular cone that has a height of 11.7m and a base with a circumference of 9 m.

Approximately 25.1 m^3

Step-by-step explanation:

The volume of a cone is . We know the height, but we don't know the radius. Fortunately, we are given the circumference of the base circle.

Now that we have the r, we can plug it into the volume equation.

After you plug this into the calculator, you get approximately 25.1 m^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
