When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3
1. PEMDAS, exponents first
2^3=8
2. multiply
8x2=16
3. subtract
16-3=13
Hope this helps!
Answer: 1
Step-by-step explanation: It is 1 because according to order of operations we have to do what is inside the parentheses first, so we do 2x2 + 2x2, which equals 4+4=8, finally do 8/8 to get 1.

Answer:
Radius of the cone = 16 m
Step-by-step explanation:
Slant height of the cone 'l' = 5 m
Curved surface area of the cone is represented by the formula,
Curved surface area = πrl
Here r = radius of the circular base of the cone
l = slant height of the cone
By putting the values in the formula,
251 = πrl
251 = πr(5)
r = 
r = 15.979
r ≈ 16 m
Therefore, radius of the given cone will be 16 m.
