For every centimeter that is drawn, it corresponds to 1 meter in real.
Knowing that every meter has 100 centimeters:
1:100
The angular velocity by definition is given by:
w = rev / t
Where:
rev: revolutions
t: time
Substituting values we have:
w = (6 * (2 * pi)) / (12)
w = 3.141592654 rad / s
Answer:
the average angular velocity of the spinner, in radians per second, for the 12-second interval is:
w = 3.141592654 rad / s
I think it’s b.
Sorry if I’m wrong .
1 cm is the base of the triangle
Answer:
Draw the line segment AB = 7 cm.
Draw ray BX making an acute ∠ABX.
Along BX. mark off five points B1, B2, B3, B4 and B5. Join B2 to A.
Through B5 draw B5P || B2A, intersecting BA produced at P.
The point P so obtained is the required point which divides AB externally in the ratio 3:5.
