Question 1:
Circumference = 3.14 x diameter
C = 3.14 x 17
C = 53.38 m
Question 2:
Circumference = 3.14 x diameter (or 2 x radius)
C = 3.14 x 6
C = 18.84 ft
Question 3:
The radius of a circle is equal to half its diameter.
10 / 2 = 5 cm
Question 4:
We want to find the perimeter of the shape as a whole. We will need a half circumference for the circular part, and 3 sides of the rectangle.
C = 1/2(3.14 x 6) = 9.42
6 + 4 + 4 = 14
Perimeter = 9.42 + 14 = 23.43 ft
Hope this helps! :)
