Mathematics

We would first have to find the area of pizza(πr^2),then devide it by ten,which would make the equation:

[π(18÷2)^2]÷10
=(9^2π)÷10
=81π÷10
=8.1π inch^2

Thus the answer is 8.1π.

Hope it helps!

Hey!


First, let's find the area. The formula for finding area of a circle is: π · r²


Radius is ½ of the diameter. Divide the diameter by 2 to get the radius.


d = 18

18 ÷ 2 = 9


r = 9

r² = 9 × 9 = 81


The area of the whole pizza is 81π. There are 10 slices. Divide the area of the whole pizza by 10 to find the area of 1 slice.


81π ÷ 10 = 8.1π


<em>That means each slice is 8.1π inches²</em>

Ray wants to buy an item worth $500. Which option is the most cost-effective?
LuckyWell [14K]

Ray wants to buy an item worth 500$ in the most cost-effective way. Let's study each of the 3 cases and see with option is the best.

In the first option, he'll buy the item at list price with a coupon for $10 off. So he'll buy it at 500-10 =$490.

In the second option, he'll buy a membership for $35 and then get the item at a 15% discount. With a 15% discount, the price of the item will be 500 - (500*0.15) = 500 - 75 = $425. And with the membership price, he'll pay a total of 425 + 35 = $460.

The third option is to buy the item online at a 10% discount and pay $4 for the shipping. At 10% discount, the price of the item will be 500 - (500*0.1) = 500 - 50 = $450. And with cost of the shipping, he'll pay a total of 450+4 = $454.


So if he chooses the first option, he'll pay $490. With the second, he'll pay $460. And finally with the third, he'll pay $454.

So the third option is the most cost-effective, buying the item at $454.

Hope this helps! :)
