The last option should be correct
6x6x6=216
3.14x(2)^2=12.57
216-12.57=203.43
The process is to find the volume of the cube then subtract the volume of the cone inside it.
Answer:
D
Step-by-step explanation:
(-8)^-2 would be 1/-64 not 1/64
Answer:
y= 2x+5
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient. Hence m=2.
Subst. m=2 into the equation:
y=2x +c
Now substitute a coordinate.
When x= -2, y=1,
1= 2(-2) +c
1= -4 +c
c= 1 +4
c=5
Thus, the equation of the line is y= 2x +5.
