Answer/Step-by-step explanation:
Formula:
C = 2πr
Note: π = 3.14(About)
-------------------------------------------------------------------------------------------------------------
[3] It given that the diameter is 16 ft.
Diameter - a straight line passing from side to side through the center of a body or figure
Radius - Half of Diameter
C = 3.14(16)
= 50.24 ft
-------------------------------------------------------------------------------------------------------------
[4] It given that the radius is 7.5 in
Radius - a line segment extending from the center of a circle or sphere to the circumference or bounding surface.
C = 3.14(15)
= 47.1 in
-------------------------------------------------------------------------------------------------------------
[5] It given that the radius is 42 m
C = 3.14(84)
= 263.76 m
-------------------------------------------------------------------------------------------------------------
As Noted : π is approximately 3.14. Thus the answers are approximately
