Find the area and perimeter
pashok25 [27]

Answer:

Part 1) The perimeter is P=172\pi\ ft

Part 2) The area is A=1,204\pi\ ft^2

Step-by-step explanation:

Part 1) Find the perimeter

we know that

The perimeter is equal to the circumference of the exterior circle plus the circumference of the interior circle

so

P=2\pi (50)+2\pi (36)

P=2\pi (86)\\P=172\pi\ ft

Part 2) Find the area

we know that

The area of the figure is equal to the area of the larger circle minus the area of the smaller circle

so

A=\pi (50)^2-\pi (36)^2

A=\pi (1,204)

A=1,204\pi\ ft^2
