#30-2 March 29, 2011 Solve the equationSimplify your answer 1) 31 = 3x + 42) 3) Complete the mapping diagram for the following graph.

Use the 10 for finding the circumference of the semi-circle. C = ∏d 2 You divide by two because it is HALF of a circle. Add the circumference of the semi-circle to the other two sides of 8 ft and 6 ft. The perimeter of this composite figure is _____ft.

C = ∏d I have 2 semi-circles. If I put them together, I have a whole circle, so I DO NOT need to divide by 2. Add the circumference to the perimeter of the rectangle. Perimeter of the Rectangle = 2 l + 2w The perimeter of this composite figure is _____m.

C = ∏d 2

Add the circumference of the 2 semi-circle to the other sides of 8 ft, 6 ft, and 10 ft. C = ∏d What are these two lengths? Add ALL the sides together.

C = ∏d 2
