Question

A circular pan has a diameter of 8 inches. What is the exact area of the pan?




























 



A.





256π square inches
























 



B.





8π square inches
























 



C.





64π square inches
























 



D.





16π square inches

Answer 1

Diameter of a circle = 2r
an area of a circle = πr²
so, if the diameter of the circular pan is 8 inches taht menas,
2r = 8
or, r = 4 inches
so area of the pan = πr² = 22/7* 4 = 12.57 inches

Answer 2

You would divide the diameter in half to get the radius which is 4. And do the formula which is a=pie(r) squared. So the answer would be 50.24
