Answer 1

area of circle Pi(R)^2 and 2piR R = radius

Answer 2

pie * radius^2

Answer 3

area of a circle is pi(3.14)

Answer 4

2piR is ur cicumference

Answer 5

is circumfrence, pi times d?

Answer 6

or is it 2 pi r or 2 pi r squared

Answer 7

ya that works to. u can use diameter or 2(R)

Answer 8

so it doesnt matter which one u use

Answer 9

pi (3.14) radius (half diameter) sqaured (to the second power)

Answer 10

ok thanx u guyzzz

Answer 11

wait... for area it has to be Pi(R) squared.. and for circumference it can either be 2(R)pi or piD

Answer 12

ok i get it now.... :)
