Answer:

A = 78.5 cm²

Step-by-step explanation:

Area of Circle = πr²

A = (3.14)(5)²

A = (3.14)(25)

A = 78.5 cm²

The area formula of a circle is r² x π.

With that being said, we can now substitute in our radius value.

(5)² x π

From there, we can find the square root of the radius.

(25) x π

And then we can multiply by pi to solve.

78.539816..

Finally, we'll round to the nearest tenth to get our answer.

78.5

Therefore, the area of the circle is 78.5 cm.

<em>Hope this helped! :)</em>

Read the following statement: Line segment CD is congruent to line segment EF. Which of the following is an equivalent statement
Natasha_Volkova [10]

An equivalent statement is CD overbar congruent to EF overbar.

What is a line segment?

The line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.

Here,

Line segment CD is congruent to line segment EF and in geometry, an overbar represents a line segment.

So, we can say that the CD overbar means line segment CD and the EF overbar means line segment EF.

Hence, An equivalent statement is CD overbar congruent to EF overbar.

Answer:  \text{quadrilateral FSHB}\sim\text{quadrilateral KTWJ }

Step-by-step explanation:

To polygons are said to be similar if all the corresponding angles of given polygons are equal.

In the given figure, it can be seen that in quadrilateral FSHB and quadrilateral KTWJ all the corresponding angles are equal.

∠F=∠K

∠S=∠T

∠H=∠W

∠B=∠J

Therefore, The given polygons are similar.

Hence, \text{quadrilateral FSHB}\sim\text{quadrilateral KTWJ }
