49/16, of course.
16:49
It is 16/49 which cannot be simplified.

False: Ratio areas= 16 : 64 = 1 : 4 Ratio of sides = sqrt(ratio of areas) = 1 : 2
The ratio of their surface areas is 42 to 52 or 16 to 25
The ratio of their surface areas is the square of the ratio of the lengths. Since the ratio of the lengths is 4-1, then the ratio of the surface areas is 4^2-1^2 or 16-1.
The ratio is 16 to 81.
Ratio of circumference is π : 4π = 1 : 4 This is the ratio of all lengths, therefore their radii are in the ratio of 1:4 also. Ratio of areas is the square of the ratio of length → ratio of their areas is 1² : 4² = 1 : 16
If the length ratio is 2:7 then the area ratio would be 4:49, squaring the 2 and the 7.
The term "ratio of 49" is somewhat ambiguous without additional context. If you're referring to the number itself, 49 can be expressed as a ratio of 49:1 or simply as 49. If you meant the ratio of 49 to another number, please specify that number for a more accurate answer.
16:1
No. 4/7 and 16/28 and 28/49 are equivalent ratios. The 4 and the 7 must be multiplied by the same number in order to maintain the ratio.
