What is the approximate circumference of the pizza? Use = 3.14.

OpenStudy (anonymous):
yes please
OpenStudy (anonymous):
To get the approximate circumference of a circle the fomula is
(3.14) (r^)
The diameter is 21 but we must find the radius so therefore, we 21/2 which then equals 10.5
so now (3.14) (10.5^2)
We multiply 10.5x10.5x3.14 which leads to the answer of 346.185
If i was confusing at some point, please tell me :)

^ is like the exponent per example. |dw:1427490306495:dw|
