Answer:
16
Step-by-step explanation:
Total surface area of a cone T1 = πr(r+l)
If the radius and the slant height of this right circular cone are each multiplied by 4, the new surface area will be expressed as;
T1 = π4r(4r+4l)
T2 = 16πr(r+l)
Taking the ratio of both total area
T1/T2 = πr(r+l)/16πr(r+l)
T1/T2 = 1/16
16T1 = T2
T2 = 16 T1
Hence the total surface area is multiplied by a factor of 16
Answer:
Choice C
Step-by-step explanation:
Divide both sides by -3.55; remember that by dividing both sides of an inequality by a negative sign, you need to change the direction of the inequality sign.
Answer: Choice C
