Question

The transportation department has to put a railing along the outer curve of this road. The road is 20 feet wide. What is the length of the outer curve to the nearest foot? Use the value = 3.14

Answer 1

the length of the outer curve is 86 feet

Answer 2

L = 85.85

Step-by-step explanation:

figure relate to this question is attache below

so, radius for outer curve is 70 ft

we know that

`arc\ length = radius * angle`

angle is given as 70 degree, convert degree to radian =
`70 * (\pi)/(180)`

`L = 70 * [70 (\pi)/(180)]`

L = 85.85
