Answer:

The answer is 10.5

Step-by-step explanation:

Answer:

311 $cm^{2}$

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 = $\pi r^{2}$ where r is the radius

taking $\pi$ to be 3.14

hence area x = 3.14 ( $\frac{36}{2}$ * $\frac{36}{2}$ ) = 1017.36

Area y = 3.14 ( $\frac{30}{2}$ * $\frac{30}{2}$ )= 706.5

x-y = 1017.36- 706.5 =310.86 $cm^{2}$

310.86 $cm^{2}$
