Question

How much more area does a large pizza with a 12 in. diameter have than a small pizza with an 8 in. diameter? Round your answer to the nearest square inch.

Answer 1

Answer: About 63 in²

Explanation:

Area of circle = π · r²

• r = radius length
• π ≈ 3.14

Area of large pizza:

`\pi *r^(2) =3.14*6^(2) =3.14*36=113.04`

Area of small pizza:

`\pi *r^(2) =3.14*4^(2) =3.14*16=50.24`

Difference in area:

`113.04-50.24=62.8`
