<span>π x d, the diameter of this circle is 22.
22 x 3.14 = </span>69.08, but this must be divided by two as it is a semicircle.
69.08/2 = 34.54,
so 34.54 is the perimeter of your semicircle now you must add all the lengths and widths together to get your perimeter.
22+31+31+34.54=<span>118.54

the gardener will need 118.54ft of fence to go around the garden
Answer:
Step-by-step explanation:
A) Let x represent minutes used, and C represent monthly charge. We are given two (x, C) pairs: (370, 133.00) and (530, 181.00)
We can use these in the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
C = (181 -133)/(530 -370)(x -370) +133
C = 48/160(x -370) +133
C = 0.30x -111 +133
C = 0.30x +22
__
B) For x = 477 minutes, the charge will be ...
C = 0.30(477) +22 = $165.10 . . . . for 477 minutes

Answer:
0.40x = 320
Step-by-step explanation:
40% as a decimal is 0.40.
Let the number of house plants = x.
40% of the number of house plants is 320.
40% * x = 320
0.40x = 320
