Answer:

$3.19

Step-by-step explanation:

so he starts with $18.90 and we know that he spent $2.95. So we will subtract $2.95 from $18.90. So we are left with $15.95. But now its says he bought 5 items with $15.95. So we will divide 15.95 by 5. So the price of the item that he bought 5 of is $3.19

If you are at a higher level you can use this method:

make and equation of: 5x + 2.95 = 18.90

with this you would subtract 2.95 and then divide by 5 just like we did above.

Answer:

d. 15.95

Step-by-step explanation:

So if one item cost $2.95 and he bought 5 other items that were the same price, we first have to subtract $2.95 from the total which is $18.90.

18.90 - 2.95 = 15.95

Now, to find the cost of the other five items we divide the amount of money left by 5.

15.95 / 5 = 3.19

So each of the other five items costs $3.19.

To find the total cost of the five items together, we multiply 3.19 by 5.

3.19 x 5 = 15.95

The volume of the cone is 18π

Option A is the correct answer.

What is a cone?

It is a shape of a christmas tree where there is a base of radius r and a top point called the apex.

The volume of a cone is V = (1/3)πr²h

We have,

The formula for the volume of a cone is:

V = (1/3)πr²h

where V is the volume, r is the radius, and h is the height.

Plugging in the given values, we get:

V = (1/3) x π x 3² x 6

V = 18π

Therefore,

The volume of the cone is 18π
