Step-by-step explanation:

a radius is a line halfway through the circle starting in the middle... a diameter is double that, or a line that goes all the way through the circle

you are working with diameter

in order to find the circumference of a circle using diameter, the equation is

C (circumference) = pi x d (diameter)

in order to find the circumference of a circle using radius, the equation is

C = 2 x pi x R (radius)

Answer:

Use the equation found in step 3 and the remaining information given in the problem to answer the question asked. In this case, you need to find x when y = 44 and z = 6. Example 2 – If f varies directly as g and inversely as the square of h, and f = 20 when g = 50 and h = 5, find f when g = 18 and h = 6.

The perimeter of a figure is the distance all the way around the figure.

Area is how many units takes up the figure.

Example of perimeter: (attached)

Example of area: (attached, with squares in square)

In this case, the area depends on the perimeter. Count two sides of the rectangle. (Horizontal, and vertically.) Then write what the perimeter is for that. Multiply the two numbers and that will be your area.

Vertically, it is 11. Horizontally, it is 9. I would like you to try to see what to do next, if not, comment!

I hope this helped!

Joel sells ice cream cones at the county fair. He has to rent the equipment for $28 and spent $.33 on a gradients for each accou

spin [16.1K]

Rental - $28
Ingredients- $33
Total $61.00

At $1.30 each you can guesstimate he'd have to sell almost 60 cones to break even.
OR
You can divide 1.30 into $61.00 for about 47 cones to break even. (I rounded up)

To make a profit he would either need to sell double that amount or he could raise the cost of his cone to $2.00 & make profit sooner.
