THe hypotenuse of the triangle is the diameter of the circle.
Area=28
Altitube (base)=4
equation:

We have to find h:

2h=14
h=7
Find the diameter of the circle using pythagoren theorem:

d=8.1 (rounded)
Try to find the area and cirmuference by yourself using and points given are diameter = 8.1 radius = 8.1/2
