## sshackiraa Group Title Determine how many slices you will cut your pizza into. You need to pick two different numbers of slices. Once you have determined the number of slices, calculate the following for both ways of cutting your pizza: • the interior angle and arc length of the slices • the area of each slice 2 years ago 2 years ago

Determine the delivery radius for your shop. Draw a point on a coordinate plane where your shop will be located. Create two different radii lengths from your shop, and construct the circles that represent each delivery area. How much area will each delivery radius cover? Write the equation for each circle

Seems like one of those "do it yourself" problems to me.

3. sshackiraa Group Title

I really don't understand how to do this tho :(

@inkyvoyd, help her

5. inkyvoyd Group Title

Let's start with a couple of things 1. The formula for the area of a circle and sector 2. The formula for the arc length of a circle 3. The equation of a circle centered at (h,k) @Hero , your turn. Alternatively, @lgbasallote

I got like 9 minutes, and I have about 3 days worth of online coursework to catch up on for the moment. Let me retag that igbiw. @lgbasallote

First, pick any random number to determine the size of the pizza, we know that a circle is defined by 1 thing, the radius; then, pick the number of slices.

Let me make the first example, I have a 14cm radius pizza, and I want 3 slices. First off, we know that a circle has 360 degrees inside. 3 equal slices, so 360/3 = 120 degrees for each slice. |dw:1337224132502:dw| Then, to find a arc length of each slice, we can use the little formula we are going to invent by ourselves, Circonference $$\div$$ Number of slice = Arc length of each slice The formula to find the circonference of a circle is $$2 \pi r$$ Let's plug our radius in, $$2 \pi 14=28 \pi$$ Okay, cool, we have our circonference, 3 slices. Apply our little formula, Circonference $$\div$$ Number of slice = Arc length of each slice; $$28 \pi \div 3 \approx 29.32cm$$ So the arc length of each slice would be 29.32cm. Next, the area, simple use the formula $$\pi r^2$$.

And for the shop problem, as I haven't learn ellipse yet, I can't help you out for this one. @Callisto can you help for that last part?

Ok, thank you so much ! :)
