Answer:
84 degrees
Step-by-step explanation:
Applying the Cosine Rule (Choice 2 is the correct one) :-
12^2 = 11^2 + 6^2 - 2*11*6 cos Y
144 = 121 + 36 - 132 cos Y
cos Y = (121 + 36 - 144) / 132
cos Y = 0.09848
Y = 84.3 degrees
Answer:
- 65.312 inches
- 326.56 inches
- 1959.36 inches
Step-by-step explanation:
<h3>Given</h3>
<h3>To find</h3>
- Travel in 1, 5, 30 rotations
<h3>Solution</h3>
<u>Circumference of the wheel is equal to one full rotation</u>
- C = πd = 3.14*20.8 = 65.312 inches
- 5C = 5*65.312 = 326.56 inches
- 30C = 30*65.312 = 1959.36 inches
