Find the circumference of each circle given its radius or diameter. (Round your answers to two decimal places.)
(a) d = 18 in
____in (b) r = 6 m
_____m (c) 10 cm
_____cm (d) 2.5 ft
______ ft
a) Circumference = 2pi * r = 2 pi * (d / 2) = pi * d = pi * 18 in ≈ 56.55 in
b) 2 pi * (6) = 12 pi in ≈ 37.70 in
Again....c and d don't specify if these are radii or diameters....
Here’s C and D Hgt
I believe C is = 43.98
