Answer:

A. 31.4 feet

Step-by-step explanation:

The formula for circumference is given by

C = pi d

Since we know the diameter is 10 ft

C = pi * 10

pi  is approximately  3.14

C = 3.14* 10

C = 31.4 ft

The shape is a rectangle, will you please help me find the angle measures of 1,2 and 3?
Ulleksa [173]

Answer:

  ∠1 = ∠3 = 54°; ∠2 = 36°

Step-by-step explanation:

Each of the triangles is isosceles. Triangles opposite each other are congruent, so ∠2 is congruent to 36°.

∠2 and ∠3 are complementary, so ∠3 is 54°. Since ∠3 is congruent to ∠1, it, too, is 54°.

The American flag is customarily made with its width and length in the ratio of 10 to 19. Which of the following dimensions is i
saul85 [17]
You have not provided the options, therefore, I cannot give an exact answer. However, I can help you with the procedures.

We are given that the ratio between the width and the length of the flag is 10 to 19.
This means that:
\frac{width}{length} =  \frac{10}{19}

Therefore, to get the correct choice, all you have to do is divide the width by the length, if the result is 10/19, then the dimensions given are correct.

Examples:
For length = 190 and width = 100,
width / length = 100 / 190 = 10 / 19 .........> correct choice

For length = 1.9 and width = 1,
width / length = 1 / 1.9 = 10 / 19 .......> correct choice

Hope this helps :)
