a pizza is 22 cm and a third of it is covered in cheese what area is that that has been covered in cheese
I will assume that the diameter of the pizza is 22 cm, so the radius r is 11
Area of whole pizza = pi(11)^2
= 121pi cm^2
= appr. 380 cm^2
so 1/3 of that is 126.7 cm^2
BTW, do not use your real full name on here, pick some type of nickname or just your first name
