so if the radius is 5 so to find the area we have to multiply pi(3.14) and 5 and then square it and for the circumference since we dont have the diamiter we have to do 5 times 2 and then we have our diamater so then we multiply it by the by 3.14 then we get our answer which is area=246.49 circumference=31.4
hey guys i brought some pizza for the class
your the best!
thank you billy that was very thoughtful but since this is a math class you FIRST calculate the circumference and the area before we dig in
pi x r squared sounds like area when i need a circumfrence i just use pi x d
