Answer:
D point is (0,4)
Step-by-step explanation:
WE need to find the point D from the given graph
WE look at the point D
Point D is on the y axis ( vertical line)
The point D is at 4 on y
So the value of y is 4
point D can be written as (x,y)
Here the point D is in y axis
the value of x=0
Also we know y = 4
So point D is (0,4)

Answer: $70.73
Plug in the points x and y
Circumference = 2 x pi x r
Radius, r = 7/2
Circumference = 2 x 22/7 x 7/2
= 22 cm
