Answer:
A. cos(4sinx-1) = 0
Step-by-step explanation:
use the double angle formulas and find that it is cos(4sinx-1)=0
Answer:
C = 65.97 in; r = 10.5 in
Step-by-step explanation:
The circumference is C = πd. Since the diameter is 21 in, the circumference is C = (3.14)(21 in) = 65.97 inches.
The radius is half the diameter:
r = (21 in) / 2 = 10.5 in
