The original area of a face would be a^2. Now that you added b to the edge, the new area of each face would be (a+b)^2. To find how much the are increased, subtract a^2 from (a+b)^2. 
So the answer is b(2a+b)
Supplementary = 180°
Complementary = 90°
180° - 52° = 128°
90° - 52° = 38°

Answer:
7/80
Step-by-step explanation:
(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P ( green or yellow ) = number of green or yellow / total
= (3+4)/20 = 7/20
Replace
so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P (blue) = number of blue/ total
= 5/20 = 1/4
P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80
Answer:
1282.81824016
Step-by-step explanation:
Find the volume of the cone (the formula is π×r²×h/3) and the volume is 359.19
Now find the volume of the cylinder which is 923.6282401554 and we just add them together which is 1282.81824016
