Given parameters:
Radius of the pizza = 15cm
[tex]\pi[/tex] = 3.14
Unknown:
Approximate circumference of the pizza = ?
Solution:
The pizza is circular and we take the circumference of a circle to find that of the pizza;
Circumference of a circle = 2 [tex]\pi[/tex] r
Input the parameters and solve;
Circumference of a circle = 2 x 3.14 x 15 = 94.2cm
The circumference of the pizza is 94.2cm
