Answer: 135/pi

Step-by-step explanation: Circumference is 16pi. So then 6/16pi is the fraction of the 360 arc measure of the entire circle that is the angle measure of the arc, so we multiply 6/16pi times 360 and yield 135/pi. Hope this helps!

A pyramid has a square base with sides 100 feet long. The original height was 75 feet.
viva [34]

Step-by-step explanation:

<u>Step 1:  Find the volume of the original pyramid</u>

<u />V = a^2*\frac{h}{3}

V=(100)^2*\frac{75}{3}

V=10000*25

V=250000

<u>Step 2:  Find the volume of the cut off</u>

<u />V=(20)^2*\frac{15}{3}

V = 400*5

V=2000

<u>Step 3:  Find the percent that still remains</u>

<u />250000-2000

248000

248000 / 250000

0.992*100

99.2

Answer:  99.2%

Organize the following polynomial expressions from least to greatest based on their degree: x 2xyz 3x y z 2x3y y2x − 3x 4 9x3yz
bazaltina [42]

Using polynomial concepts, it is found that the sorting of the polynomial expressions from least to greatest based on their degree is given by: I, III, II, IV.

<h3>What is the degree of a polynomial?</h3>

The degree of a polynomial is given by it's largest exponent.

In this problem, the <em>polynomials </em>are given by:

  • I: x + 2xyz.
  • II: 9x³y².
  • III: 18x² + 5ab - 6y
  • IV: 4x^4 + 3x^2 - x - 4

Hence, the respective degrees are: 1, 3, 2, 4, and the ordering from least to greatest is: I, III, II, IV.
