he Garcia family bought 400 yards of fencing to enclose a circular wildflower garden. They will use all of the fencing. a. What is the diameter of the garden? b. Use your answer to part a to find the area enclosed by the fence?

9514 1404 393

Step-by-step explanation:

The diameter can be found from the circumference using the relation ...

  C = πd

  d = C/π = (400 yd)/π ≈ 127.32 yd . . . . diameter

The area is ...

  A = πr²

where the radius (r) is half the diameter.

  A = π(63.662 yd)² ≈ 12,732.4 yd² . . . . area

Additional comment

We have used a full-precision value for pi. If you use 3.14, your answers will be different. Your diameter will be about 127.4 yards; your area about 12,738.9 yd².

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
