Forgive me if this has been asked, but I searched for pi and Math.PI and class and float and couldn't find anything relevant.

Problem as follows:

input:

a number which is a radius

output:

area and circumference of the circle with input as radius

volume and surface area of the sphere with input as radius

I got a working class, but when I attempted to change the variables to floats, in the interest of learning, it errored out. The reason is that Math.PI yields a double. I tried:

float pi = Math.PIF

That doesn't work. The only way I was able to have a working class using floats, I had to initialize pi as follows:

pi = 22/7F

Is there a way to use Java's Math.PI as a float?
