Question

What is the equation of the circle centered at the origin with a radius of 7.5 PLEASE HELP!

Answer 1

Answer: Are you talking about Circumference?

If it is then the Formula is 2πr or the easy way ... πd

1st use of formula: you would multiply 7.5 twice then multiplying by Pi or 3.14

2nd use of formula: You would get the diameter then multiply it by Pi or 3.14

Hope this helps :)
