Sorry it took me so long im actually doing something myself. Area for a circle is πr 2 what exatly are you having problems with?

anonymous · Answer

The area for circle is Pi r2

anonymous · Answer

im just not sure i think its rational but then again  i don't and its okay :)

anonymous · Answer

It is rational Because when you solve out the problem its like this:

0.75*0.75= 0.5625 (thats the r2)

then you mutiply Pi as well

After you multiply it will be 1.77

Which is not irrational

thank you :)

because An irrational number has endless non-repeating digits to the right of the decimal point
