Answer:
B. 
Step-by-step explanation:
Given,
The number of smaller cubes = 
So, the number of cubes that have no coloured faces. =
,
Note : If a cube painted outside having side n is split into n³ cubes, then the volume volume that is not painted = (n-2)³
Thus, the remaining cubes that have been painted red on at least one of their faces
= Total cubes - cubes with no painted face



Hence, OPTION B is correct.
Answer:
{(2,-1), (4, -2), (6, -3), (8, -4)}
Step-by-step explanation:
The other ordered pairs have a common domain value which means they are not a function.
For example:
{(5,7), (5,8), (10,3)} would not be a function because the 5 is repeating
However
{(2,6), (4,6), (22,7)} would be function because there are no numbers in the x part of the ordered pair that repeat. (x,y)
I hope you can see the pattern now

D. 2 radians
Remember that: Radian=arc length/radius
In your case you have
arc length=2r
radius=r
so Radian=2r/r=2
Step-by-step explanation:
- area of a semicircle=1/2(πr^2
- =1/2×22/7×6^2
- =56.54
