Help please

Step-by-step explanation:

From the attachment, we have:

To calculate the total area of the figure, we have to calculate the areas of individual shapes, then add them together

For Semicircle B

Substitute 5 for radius (r)

For Semicircle C

Substitute 5 for radius (r)

For Quarter circle DC

Substitute 5 for radius (r)

The area of the shape is:

Take LCM

Take

So, we have:

To calculate the total perimeter of the figure, we have to calculate the circumference of individual shapes, then add them together

For Semicircle B

Substitute 5 for radius (r)

For Semicircle C

Substitute 5 for radius (r)

For Quarter circle DE

Substitute 5 for radius (r)

The perimeter of the shape is:

Take LCM

Take

So, we have:

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
