Answer :
The reason you didn't find anything in your High school notes that
can help is that everything you need to answer this one is stuff
you learned in Middle school.
Forget about the big wheel and the sunshine and the cotton candy.
Also, if you're doing any trigonometry or pre-calculus, ignore that too.
-- You have a circle whose radius is 80-ft.
-- Its circumference is (2pi) x (80) = 160 pi ft.
-- Two points on the circle mark a central angle of 135 degrees.
135 degrees is ( 135 / 360 ) of a full circle.
-- So the length of the arc between the points is ( 135 / 360 ) of the
full circumference.
( 135 / 360 ) x ( 160 π feet) = 70.69 feet (rounded)
Answer:
230.4
Step-by-step explanation:
% of the circumference for the Intercepted arc = % of the circle of the angle that intercepted it
165 / 360 ≈ 0.4583 = 45.83%
Circumference = 2πr
2π80 = 502.65
502.65*45%=230.4
