Answer:
Step-by-step explanation:
[tex]C=[/tex] 2πr [tex]A=[/tex] πr²
We will be substitute 3.14 for π
Dividing the diameter by 2 will give you the radius
[tex]\frac{16}{2} =8[/tex], [tex]r=8[/tex]
[tex]\frac{12}{2} =6[/tex], [tex]r=6[/tex]
Medium Pizza:
[tex]C= (2)(6)(3.14)=37.68[/tex]
[tex]A=(3.14)(6)^{2}=113.04[/tex]
Large Pizza:
[tex]C=(2)(8)(3.14)=50.24[/tex]
[tex]A=(3.14)(8)^{2}=200.96[/tex]
