Question

A small silver dollar pancake served at a restaurant has a circumference of 2pi inches. A regular pancake has a circumference of 4pi inches. Is the area of the regular pancake twice the area of the silver dollar pancake? Explain.

Answer 1

if the circumference is 2
`\pi`, the radius is 1 because the diameter is 2. Area =
`\pi`
`r^(2)`.

2
`\pi`: A ≈ 3.14

4
`\pi`: A = 12.56

No, it is not twice the area of the smaller circle
