Answer:
616
Step-by-step explanation:
first 2 2/3 divided by 1/3 = 8 so it is 8 cubes in that direction, then 3 1/3 divide by 1/3 = 11 so 11 cubes in that direction, which gives us a layer. 2 1/3 divided by 1/3 is 7 so we need 7 layers. multiply 8 by 11 to get the number of cubes per layer, which is 88. then 88 times 7= 616.

Answer:
B)12
Step-by-step explanation:
The polar equation of an ellipse is .
The vertices of ellipse are (−1,0) and (3,0).
The polar equation of an ellipse can be represented as
where e is the eccentricity.
Eccentricity, e =
c is the distance from the center to the focus and a is the distance from the center to the vertex
⇒
⇒ c = 2
⇒
⇒ a = 1
Then, e =
⇒ e = 2
Now, the polar equation of an ellipse becomes as,
⇒ ------- (1)
Now plug in a vertex point such as (-1,0) and solve for p,
⇒
⇒ [∵ cos 0 = 1]
⇒
⇒
⇒
Thus the polar equation of an ellipse (1) becomes as,
⇒
⇒
Hence we can conclude that the polar equation of an ellipse is .
