Answer:
Graph = Cardioid
Axis of symmetry = y-axis
Critical points= 
Step-by-step explanation:
General equation for this type of cardioid is:
a ± b sinθ
Condition for a cardioid = 
Axis of symmerty according to the graph of 2 + 2 sinθ is along y-axis.
Critical points:
r = 2 + 2 sinθ ⇒ r = 2(1 + sinθ) ⇒ r' = 2 cosθ
∵derivative of 1 + sinθ = cosθ
For finding critical point the derivative is equal to zero,
2 cosθ = 0 ⇒ cosθ = 0
the value of cosθ is equal to zero at intervals:
So, critical points =
Answer:
352 m^2
Step-by-step explanation:
Each of the four congruent triangular faces has an area that is half the product of the base edge length and the slant height:
A = 1/2·bh = 1/2·(8 m)(22 m) = 88 m^2
Then the total lateral area is 4 times this:
LA = 4·88 m^2 = 352 m^2
