Answer:
311 [tex]cm^{2}[/tex]
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 = [tex]\pi r^{2}[/tex] where r is the radius
taking [tex]\pi[/tex] to be 3.14
hence area x = 3.14 ([tex]\frac{36}{2}[/tex] *[tex]\frac{36}{2}[/tex]) = 1017.36
Area y = 3.14 ([tex]\frac{30}{2}[/tex] * [tex]\frac{30}{2}[/tex] )= 706.5
x-y = 1017.36- 706.5 =310.86 [tex]cm^{2}[/tex]
310.86 [tex]cm^{2}[/tex]
