Answer:
The height of the tower is 310.6 ft
Step-by-step explanation:
since both spinners are independent from each other, we can directly multiply their probabilities for the combined event.
1)
1/5 × 1/3 = 1/15
2)
1/5 × 2/3 = 2/15
3)
2/5 × 1/3 = 2/15 (you got that wrong on your paper)
4)
2/5 × 2/3 = 4/15
5)
3/5 × 1/3 = 3/15 = 1/5
6)
3/5 × 2/3 = 6/15 = 2/5
First one:
The circumference of the whole circle is (2π x the radius),
and 60° is (60/360) = 1/6 of the whole circumference.
Second one:
The area of the whole circle is (π x the radius²), and
the 40° sector is (40/360) = 1/9 of the whole area.
I hope this is enough help.
I think the answer is B. But if I’m wrong I am so sorry :(
