Answer:
The scale factor is 3.
Step-by-step explanation:
Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).
Therefore, the distance OA is given by
units.
Again, the coordinates of point A' are (1,-2).
Therefore, the distance OA' is given by
units.
Hence, the scale factor is
. (Answer)
7.1 is ten times smaller than 71
Answer:
The radius 10 cm
Step-by-step explanation:
∵ The volume of the cone = 1/3 πr²h
∵ v = 1256 cm³
∵ h = 12 cm
∴ 1256 = 1/3 π (12) r²
∴ r² = 1256 × 3/12π = 100 cm
∴ r = √100 = 10 cm
Isn't it 1/8?
I hope this helped i think i just simplified xD
