The figures below are based on semicircles and squares. find the perimeter and the area of each shape. give your answer as a completely simplified exact value in terms of π (no approximations).

The area of the figure be 137.76 units and perimeter of the figure be  42.39 units .

Step-by-step explanation:

Formula

Where r is the radius of circle .

As the figure given in the question consist of one big and Three small semicircle .

As

As AB = BC = CD =  6

                                                   = 9 units

                                                   = 1.5 units

                                         = 28.26 + 14.13

                                         = 42.39 units

Area of the figure = 127.17 + 10.59

                             = 137.76 units

Therefore the area of the figure be 137.76 units and perimeter of the figure be  42.39 units .

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
