Calculate the perimeter of a semi-circle
whose diameter is 14cm

Perimeter of semi-circle = 36 cm

Step-by-step explanation:

diameter = d = 14 cm

Perimeter of semicircle = Circumference of semi-circle + diameter

                                       =

                                       =

                                       = 22 + 14

                                       = 36 cm

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
