Acircular stained glass
window has a diameter of 5
feet. what is the area, in
square feet, of the stained
glass window?
g
h.
15.7 square feet
19.63 square feet
31.40 square feet
61.62 square feet

19.63ft²

Step-by-step explanation:

Area of a circle = πr² where π = 3.142 or 22/7 and r = 5/2 because 2 radii makes one diameter.

Now, the area = 3.142 x (5/2)²

                       = 3.142 x 25/4

                       = 19.63ft²

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
