PLEASE HELP ME WITH THIS MATH QUESTION

Answer:

Arc length is $\frac{14\pi}{3}$ , or, 14.7

Step-by-step explanation:

AB is an arc intercepted by 140 degree angle. The formula for length of an arc is given by

$AL=\frac{\theta}{360}*2\pi r$

Where

AL is the arc length

$\theta$ is the angle (in our case, 140)

r is the radius of the circle (which is 6)

Substituting, we get:

$AL=\frac{\theta}{360}*2\pi r\\AL=\frac{140}{360}*2\pi (6)\\AL=\frac{7}{18}*12\pi\\AL=\frac{14\pi}{3}$

In decimal (rounded to tenths) - 14.7

I need help plz no one in my class understands it?

grandymaker [24]

Because none of those are the right answer. you are given units in feet in the diagram. but are told 6 inches are lost in 4 hours. so you multiply length width and height keeping the feet then subtract .5 ft. the equation should look like V=(12×7×8)-.5
