A circular plate has circumference 17.6 inches. What is the area of this plate? Use 3.14 for piπ. WILL MARK BRAINLIEST ANSWER! ⭐️

24.62 in^2

Step-by-step explanation:

The area of a circle is A=pi*r^2

Circumference is C=2*pi*r

Given a circumference of 17.6 inches, we get:

17.6=2*3.14*r

17.6=6.28r

2.8025=r

Given a radius of roughly 2.8 inches, we can find the area:

A=3.14*2.8^2

A=3.14*7.84

A=24.6176

So the area is around 24.62 in^2

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.
