Area of any circle = pi*radius2
The question is misguided. You do not use radius only on circles!
step 1: if its an open cylinder you have to find the area of both circles by doing radios times radios times pie. (pie equals 3.14). you do this for both circles. step 2:then you find radios the radios of the rectangle
i cant get the pie sign so whenver theres a ^ it means pie (3.14....)JUST REMEMBER.....Cherry pies are delicousC=^dcircumferance= pie times diameterapple pies are too!A=^r2area= pie times radius 2
It is important to know formulas of pi for circles like areas of a circle and its circumference
