Answer:
Volume of a circle = approximatley 25.12
Step-by-step explanation:
1. Volume of a circle= 4/3*pi*radius
2. Radius equals 1/2 of diameter
3. 12/2=6
4. radius=6
5. 4/3*3.14*6=25.12
6. Volume of a circle = approximatley 25.12
Answer:
4
Step-by-step explanation:
If you replace x with 3 in the expression you will get an indefenite form (0/0)
So there two methods.
The easiest one is applying The hospital rule
Derivate the expression firsr but separatly.
● (x^2 -2x -3)' = 2x - 2
● (x-3)' = 1
When x tends to 3
Lim(x^2-2x-3/x-3) = lim (2x-2/1) = 6-2 = 4
16-4=12
8x=12
÷8
x=12/8
x=3/2
x=1.5
