Answer:
the top answer
Step-by-step explanation:
right hand Riemanns are an over approximation, so it would include higher number sets.
Answer:
the first option
Step-by-step explanation:
solution:
distance: d=1/4 lc (because is a quarter of a circle)
length of the circumference: lc=2 pi r
pi: constant=3.14
radius of the circle: r=80 feet
replacing pi and r in the formula of lc:
lc=2 pi r
lc=2 (3.14) (80 feet)
lc=502.4 feet
replacing lc in the formula of d:
d=1/4 lc
d=1/4 (502.4 feet)
d=502.4/4 feet
d=125.6 feet
For this you have to get r by itself so you put 1 over 3 and move it to the other side and then you get 2/3 as an answer
