Question

A round pizza with a 14" diameter is cut into 8 congruent slices. What is the area of one slice/sector? (in termsof pie)

Answer 1

So, we know:

Diameter =14

Radius =7 (Half of the diameter)

`\text{Area}=\pi r^2`
`\text{Area}=\pi(7in)^2\text{ =49}\pi in^2`

Now we divide by the number of slices to get tha area of the slice:

`\frac{49\text{ }\pi\text{ in}}{8}\text{ = }(49)/(8)\text{ }\pi in^2`

So the answer is b.
