The domain of this equation is the lowest x value to the highest x value. For example: lowest is -4 and highest is 3. You would write it as [-4,3]
For this equation, the domain is (-infinity,infinity) because there is no lowest or highest x value.

Answer:
Volume = <u>2714.34</u>
Step-by-step explanation:
This is answer because the formula to finding cylinder volume is: 
h
Radius = 
Radius = 12
12 squared = 144
144*6 = 864
864
= <u>2714.34</u> (rounded)
Answer:
The lengths of the sides are 12cm, 28cm and 36cm.
Step-by-step explanation:
Let the smallest side be 4x, the middle side be 7x and the largest side be 9x.
Smallest side + middle side + largest side = 60cm
4x + 7x + 9x = 60
20x = 60
x = 60 ÷ 20
x = 3
Smallest side (4x) = 3 × 4
= 12
Middle side (7x) = 7 × 4
= 28
Largest side (9x) = 9 × 4
= 36
1 inch = 6 miles
4 inches = ? miles
1 = 6
2 = 12
3 = 18
4 = ?
