Step-by-step explanation:
Taking a pizza to be a circle
Area of big pizza be x abd are of small pizza be y
hence difference = x-y
Area of a circle =
where r is the radius
taking
to be 3.14
hence area x = 3.14 (
*
) = 1017.36
Area y = 3.14 (
*
)= 706.5
x-y = 1017.36- 706.5 =310.86 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
