The ratio of the circumference to the diameter is defined as pi
pi=circumference/diameter
that is how they got pi
in this question it woul be 15.7/5 which would be 3.14,
c=2pir
a=pir^2
c=2pir=16pi
divide both sides by 2pi
r=8
a=pir^2
a=pi8^2
a=pi64
a=64pi in²

Step-by-step explanation:
So this triangle is considered a "special triangle". The 30-60-90 triangle rule states that if the short leg is n, then the hypotenuse is 2n and the long leg is n√3.
In this case, since the short leg is 7, x = 14 and y = 7√3. The correct answer that has this is B.
1) The second because Its the cheapest
2) The third one because the delivery fee is a one time and then all the pizzas would be cheaper than the other places.
