Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts if Ivan uses the same total number of yards for each
mixas84 [53]

Answer:

9 yards

Step-by-step explanation:

Let the length of each quilt be 'l'.

Given:

Length of green felt (g) = 15 yards

Length of blue felt (b) = 12 yards

Total number of quilts = 3

Now, the length of 3 quilts is given as:

Total\ length=l+l+l=3l ----- (1)

As per question:

Total length = Length of green felt + Length of blue felt

Total length = g+b

Total\ length=15+12=27--------- (2)

Now, comparing equations (1) and (2), we get:

3l=27\\\\l=\frac{27}{3}\\\\l=9\ yards

Hence, each quilt measures 9 yards in length.

<h2></h2><h2>Given that</h2>

Circle o has a circumference of 36π cm.

<h3>We have to determine</h3>

What is the length of the radius, r?

<h3>According to the question</h3>

Circle o has a circumference of 36π cm.

The length of the radius of the circle is determined by the following formula;

\rm Circumference = 2\pi r

Substitute all the values in the formula;

\rm Circumference = 2\pi r\\&#10;\\&#10;36\pi =2\pi r\\&#10;\\&#10;r = \dfrac{36\pi }{2\pi }\\&#10;\\&#10;r = 18 \ cm

Hence, the length of the radius of circle o is 18 cm.
