A = pi * r^2.....r = radius and pi = 3.14
A = (3.14)(13^2)
A = 3.14(169)
A = 530.66
The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is

-------------------------------
The range is

since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.
Answer:
sphere volume = 3052.1 in³
Step-by-step explanation:
sphere volume = 4/3πr³ = 4/3(3.14)(9³) = 3052.1 in³
Answer:
in order from images displayed, x = 20, x = 6, x = 5.5
Step-by-step explanation:
4x - 8 + 6x - 12 = 180
10x -20 = 180
10x = 200
x = 20
5x - 1 = 29
5x = 30
x = 6
14x - 6 = 12x + 5
2x = 11
x = 5.5
Answer: 1,200,000
Step-by-step explanation
1 meter is 1000 kilometers and the track is 400 meters long, so you must multiply 400*1000=400,000
She danced around 3 times s you must multiply 400,000*3=1,200,000
