Answer:

C) 314 feet.

Step-by-step explanation:

We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.

The distance around the track would be equal to circumference of circle.

\text{Circumference of circle}=2\pi r, where r represents radius of circle.

Since we have been given across distance, so it will be diameter of track.

To find radius we will divide across distance by 2.

r=\frac{100\text{ ft}}{2}=50\text{ ft}

Upon substituting our given values in circumference formula, we will get:

\text{Circumference of circle}=2\times 3.14\times 50\text{ ft}

\text{Circumference of circle}=100\times 3.14\text{ ft}

\text{Circumference of circle}=314\text{ ft}

Therefore, the distance around the track is 314 feet and option C is the correct choice.

Find a. Round to the nearest tenth.
Kazeer [188]

9514 1404 393

Answer:

  21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

  a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

  a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

__

We need to know the angle A. Its value is ...

  A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

  a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

  a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.
