Ms. michaels made an apple pie with a radius of 5 inches. she cut the pie into six equal slices. find the approximate area of each side.

13.09 square inches

Step-by-step explanation:

Pie is a circle and area of circle is given by  

Total area of pie =

This is divided into 6 equal pieces, so each piece has an area of:

Thus, approximate area of each side (slice) is 13.09 square inches

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

$9.41
