Question

Someone help please?

Answer 1

The figure below shows the ideal pattern of movement of a herd of cattle, with the arrows showing the movement of the handler as he moves the herd. The arc the handler makes from the starting point to the return point should be a quarter of a circle:

A sector showing a quarter of a circle is drawn. The radius is marked as 85 feet. The endpoints of the arc of the sector are marked as Starting Point and Return Point. The sector is filled with cattle.

Based on this theory, what distance will the handler move from the starting point to the return point if he creates an arc of a circle of radius 85 feet?

21.25 feet
133.45 feet
66.73 feet
88.97 feet

Answer 2

if a circle has a radius of 85 ft, then what is the circumference?

Answer 3

hint:

C = 2*pi*r
C = circumference
pi = 3.14 approximately (use more decimals to get better precision)
r = radius

Answer 4

Oh, sorry, had to go afk

Answer 5

that's ok

Answer 6

So I got 533.8 when multiplying 2 by 3.14 and 85.

Answer 7

Wait, was I supposed to have the 2 there?

Answer 8

533.8 is the distance around the FULL circle

but we only want a quarter of the full circle

Answer 9

`Wait, was I supposed to have the 2 there?`
yes

Answer 10

So if I want a quarter, I divide my answer by 4?

Answer 11

yep correct

Answer 12

Ah, okay. So then the answer would be 133.45. Thanks!

Answer 13

correct

Answer 14

Thank you for helping me through this
