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.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
