Identify which of the following sets of numbers are the sides of a triangle. Select one or more:
a. 4t, t - 2, and 2+1 when t = 3
b. 8, 13, 21
c. t - 2, 2+1, and 4t, when t = 4
d. 6.2, 7, 9

step-by-step explanation:

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
