Step-by-step explanation:

First write the question:
3a^2 + 4b^2
Substitute:
3 x (2^2) + 4 x (3^2)
Simplify:
(3 x 4) + (4 x 9)
Simplify again:
12 + 36
Answer:
48
Hope it helped :)
The scale factor would be used in solving for the volume inside the larger chest. By definition, a scale factor is considered to be the ratio of similar sides of similar figures. By using this method:
Scale factor^² = 6/4 = 3/2
Scale factor = √3 / √2
The solution would yield to a final answer of 83.7 percent larger volume compared to the smaller chest.
Answer:
30.2 aka C
Step-by-step explanation:
The formula for the area of a circle is A = pir^2. Knowing this we can create the equation A = 3.14(3.1)^2. Following PEMDAS square 3.1 to get 9.61. Then you multiply 9.61 with 3.14 to get 30.1754. When you round to the nearest tenth you get 30.2.
