Answer:

55.95 ft²

Step-by-step explanation:

Circumference formula:  C = 2πr  =>  r = C / (2π)

Area formula:  A = πr²

Substituting C / (2π) for r in the above equation, we get:

               C                        47 ft

A = π( ----------- )²  =  π ( -------------- )²

              2π                       (2π)

or ...

          π(47 ft)²                   2209 ft²

A = ----------------------  =  --------------------  =  55.95 ft²

               4π²                   4(3.14159)²

A circle has a diameter of 26 units. What is the area of the circle to the nearest hundredth of a square unit
Hitman42 [59]
To find the area of the circle, you will use the formula for finding area of any circle.

The radius is half the diameter.

A = pi x r^2
3.14 x 13^2
A = 530.66 square units

The area is 530.66 square units.

What is the reason for each step in the solution of the equation? 19=5x−119=5x−1 drag and drop the reasons into the boxes to cor
shutvik [7]
The steps are duplicated.Then, first I will write the steps in the right form:

19 = 5x - 1

20 = 5x

4 = x

Now, I will write the steps with the justification

19 = 5x - 1.... start

20 = 5x ..... Reason: addtion property of equality (you get this by adding +1 to both sides of the previous equality)

4 = x .... Reason: division property of equality (you get this by dividing by 5 both sides of the previous equality)
