13-11 = 2
15-13 = 2
17-15 = 2
As you can see, the numbers increased by two. hence the answer is 2.
I suspect 4/2 should actually be 4/3, since 4/2 = 2, while 4/3 would make V the volume of a sphere with radius r. But I'll stick with what's given:
In Mathematica, you can check this result via
D[4/2*Pi*r^3, r]
Answer:
Step-by-step explanation:
Join A and C and B and D. And add numbers to the angles formed on one of the diagonal
In triangles ABC and ADC,
Angle 1 = Angle 4
Angle 3 = Angle 2
AC = AC
Therefore, triangle ABC=ADC
Since, ABC=ADC
Similarly, triangle ABD= triangle CDB
Therefore, AB=CD and BC=DA
Answer:
$51.2
Step-by-step explanation:
3 + 4 + 1 = 8
8 x 6.40 + 51.2
(2,4) cause where the lines meet
