Yummy Pizza

As thickness is the same, the area will decide the quantity of pizzas. Hence by finding areas of both the area of larger is 4 times the smaller. hence larger pizza has greater cost.

The bigger pizza has an area of 900 pi cm, while the smaller one has an area of 225 pi cm. The smaller one costs X dollars, and the bigger one 2X dollars. Then:

X = 225pi AND

2X = 900 pi => X = 450pi

Hence, the bigger pizza is twice the area of the smaller pizza for the same price.

area of bigger pizza=4*area of larger and cost twice.so the bigger one has better price

The area of the larger one is 4 times the area of the small one. The area is proportional to radius2 the area 4 times and the price is 2 times. So per uncut area larger on is half price of the smaller one.

Well , what if the smaller one has bacon in it?

3600:2 > 900:1 that's why 60 cm. pizza has a better value

2*smaller one area=1800pi... bigger one area=3600pi

Firstly, we have to find the area of each of the pizza. Recall that area of a circle = π x radius² Hence, Area of large pizza = π(30²) = 2830cm² (3 sig. fig) Area of smaller pizza = π(15²) = 707cm² (3 sig. fig) 2830/707 = 4 (1s.f) Since the cost is just double but you get 4 times the amount of pizza, of course the large one is worth it :D

Let prize of smaller pizza be x.

Then the prize of larger pizza = 2 x

area of smaller pizza = 707

area of larger pizza = 2828 as this is four times more than the smaller one and the prize is just double.

So the larger pizza is better one.

area big one = 4 x area smaller one solver by formula: ( d^2 ) / 4 which d : diameter

Direct value of diameter should not be taken as basis for money value because for finding the size of pizza, we need square of the radius so the values change a lot after squaring and hence the size of other pizza increases more than 2 times (as thought commonly at first glance)!

volume of pizza received per unit cost will decide which of the two sizes has greater value for money. Now consider the following: 1. Volume of a uniform body= (area) .(thickness) 2. Thickness being the same for two pizzas, volume is dependent on area alone. 3. Pizza being circular, area=[(pi).(d.d)]/4, consider (pi)/4 as a constant, say k 4. So area = k.(d.d) 5. Area of smaller pizza = k.(30.30)= 900k------- (i) 6. Area of larger pizza = k.(60.60) = 3600k-------(ii) 7. We see (ii) is greater that twice of (i). But it costs only twice of (i). 8. That is , you are getting more than twice the area of smaller pizza at just twice its cost. So a bigger pizza is a better deal. Order that one :)

Sir, PSA is the short form of Problem Solving Aptitude. It is a test , which comprises of English , mathematics and science. We get marks on the basis of our performance in PSA.

THE VOLUME OF SMALLER PIZZA IS 225 PIH THE VOLUME OF GREATER PIZZA IS 900PIH SO GREATER PIZZA HAS BETTER VALUE

it is given that thickness is same, therefore the value is to be calculated only on the bases of circular area.In term of price larger pizza is double the smaller while in terms of area larger pizza is four times the smaller.

as thier thickness are same then find out the ratio between volumes of smaller/larger pizza that is 1/4 . but the ratio between price of smaller/larger pizza is 1/2 . hence the the larger pizza has greater value

area of pizza with diameter 30 is 2826 and area of pizza with diameter 60 is 11304. which is very large therefore Large pizza has good value

the cost/volume of the larger pizza is much less than that of the smaller pizza. hence.

In just doubling the cost we get 4 times the quantity of smaller Pizza.
