Answer:
A) The square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.
B) There's more crust on the square pizza then on the circle one, according to 60>50!
Step-by-step explanation:
A)First, let's calculate the area of the round pizza.
We need to find out the radius, and radius=
So radius=16/2, which is 8.
And a circle's area is , so the equation for this round pizza is:
=64
≅201
Second, we calculate the square pizza's area, which is pretty easy since the equation for a square is: .
So for this square pizza, the area would be:
=225
Lastly, we compare the two, 225>201, so the square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.
B)So this problem is actually asking you to find the circumference of the circle and perimeter of the square.
Let's start off with the circle, the formula for circumference is:
We already have the d, (diameter), which is 16, so the circumference of this circle pizza is:
16
≅50 inch
Then we find the a square's, the equation for perimeter is:
4 (side length)
=4(15)
=60 inch
So happily, we found out there's more crust on the square pizza then on the circle one, according to 60>50!
