Answer:

Step-by-step explanation:
The area of a circle is found using this formula:

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.
We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

Solve the exponent.
- (2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²

Multiply.

The area of the circle is <u>19.625 square feet.</u>
Answer:
The statements must be true are A , D , E
Step-by-step explanation:
* Lets explain the figure
- There is a triangle
- Its interior angles are x° , y° , z°
- The angle of measure w° is an exterior angle of the triangle at the
vertex whose measure is z°
- There a fact in the triangle is the measure of the exterior angle of a
triangle at one of its vertices is equal to the sum of the measures
of the two opposite interior angles to this vertex
∵ w° the measure of the exterior angle of the vertex whose measure
is z°
∵ x° , y° are the measures of the opposite interior angles of the angle
whose measure is z°
∴ w° = x° + y°
∴ w° > x°
∴ w° > y°
* Lets find the statements must be true
# w > x ⇒ A
# x + y = w ⇒ D
# w > y ⇒ E
Answer:
x = -9/23 or y = -33/23 = -1 10/23
