Answer:

28.3 (explaination below)! :)

Step-by-step explanation:

Use the formula for cicrumfrence: C=2πr

Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).

Plug in our numbers. C= 2π4.5

Then, multiply.

You'd get 28.27433388230814.

Rounding to the first decimal place, you'd have a final answer of 28.3.

Hope this helps!

How do i prove angle x and angle yzv are supplementary

yuradex [85]

Triangle XWV is an equilateral triangle(every angle is 60). So both angle V's are vertical angles, which means the are the same(60). Y is 90. So once you have 60 and 90 in triangle YZV, you know the last angle(Z) is 30. But since angle Z is 30 and angle X is 60, they are complementary and not supplementary(which adds up to 180)

Answer:

19.17 feet of lace will be leftover.

Step-by-step explanation:

Given:

Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.

Now, to find the feet of lace will be leftover.

Total feet of lace = 46.

Kaitlyn needs lace for the quilt = 322 inches.

So, by using conversion factor we change inches into feet:

12 inches = 1 foot.

322 inches = $\frac{322}{12} =26.83\ feet.$

Feet of lace she need for the quilt = 26.83.

Now, to get the feet of leftover lace:

Total feet of lace - feet of lace she need for the quilt

$=46-26.83$

$=19.17\ feet.$

Therefore, 19.17 feet of lace will be leftover.
