Given:
estimate = 140
actual = 152
Percent of error = |(estimate - actual)/actual| * 100%
% of error = |140 - 152| / 152 * 100%
= |-12|/152 * 100%
= 0.0789 x 100%
% of error = 7.89% rounded to the nearest tenth 7.9%
Answer:
C. s= 75
Step-by-step explanation:
One radian is the angle subtended by an arc length equal to the radius of the circle.
∅=s/r where s is the arc length ∅ the angle and r the radius of the circle.
Thus s=∅×r
In the circle provided arc s subtends and angle of 5 radians.
s= 5 radians× 15
=75
