Answer:
15.7 cm
Step-by-step explanation:
Circle x's circumference is 15 * pi = 47.1 cm
Circle y's is 20 * pi = 62.8
The difference is 62.8 - 47.1 = 15.7
Step-by-step explanation:
Given line is 6x+3y=15
Slope of the given line (m)=-x/y
=-6/3
=-2
let slope of the line perpendicular to the given line be m'.
Condition of perpendicularity,
m×m'=-1
-2×m'=-1
m'=-1/-2
m'=1/2
