Question

Arc

An 8 inch pie (diameter is 8) was sliced into 4 equal parts. How large is the 2 points
pie crust of one slice? *

Answer 1

6.28 inches

Explanation:

Given that the diameter of the pie=8 inch

Radius=Diameter/2

Therefore: Radius of the pie=8/2=4 Inch

Circumference of a circle
`=2\pi r`

Since the pie is sliced into 4 equal parts:

Length of the Pie crust of one slice
`=(2\pi r)/(4)`

Substituting the value of r, we obtain:

Length of the Pie crust of one slice
`=(2*\pi *4)/(4)\\=2\pi $ inches\\=6.28 inches (correct to 2 decimal places)`
