Answer 1

Answer:

Step-by-step explanation:

1)

Diameter = 6

radius = 3

we know perimeter of a circle is 2 pie r

but it a semi circle so its perimeter will be the half of the perimeter of 2 pie r

so ,

2 * 3.14 * 3 / 2 = 3.14 * 2

                       = 6.28 m

2) perimeter of the figure =

perimeter of the semi circle + perimeter of rectangle

so,

3.14 * 17/2 + 2 (17 + 5)

26.6 + 44

70.6 m (approx)

3) perimeter of the figure =

perimeter of the semi circle + perimeter of rectangle + perimeter of the semi circle  

or

perimeter of the circle + perimeter of rectangle

2 * 3.14 * 8 + 2( 16 + 8 )

50.2 + 48

98.2 m (approx)

4) perimeter of the figure =

perimeter of the semi circle (on the top , r = 4) + perimeter of rectangle + perimeter of the semi circle (on the bottom r = 2)

so,

3.14 * 4 + 2( 8 + 3) + 3.14 * 2

12.5 + 22 + 6.28

40.78 m (approx)
