Answer:
4.75 feet
Step-by-step explanation:
Let the height of the flagpole be x
Sin 53 = x/12
x = 12 × Sin 53
x = 12 × 0.3959
x = 4.75 feet
Answer:
97,175
Step-by-step explanation:
I don't think It's necessary, but I am gonna do it anyways.
15*6=90
15*7=105
105 - 90 =15
15/2 =7,5
90+7,5= 97,5
15*6,5= 97,5
0,05*6,5= 0,325
97,5 - 0,325 = 97,175
Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :

Also,

Where
is the angular speed
So,

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
