What is the measure of an interior angle of a regular three-sided polygon?
noname [10]
The formula to find the measure of an interior angle is (n - 2) * 180/n, where n represents the number of sides in the polygon. In this problem, n would represent 3. 

Let's plug in the value for n
(3 - 2) * 180/3
Let's simplify that. 
=60

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18 \pi18π18, pi
Whitepunk [10]

Answer:

A=81\pi $ m^2

Step-by-step explanation:

Circumference of the column =18\pi $ meters

Circumference of a circle=2\pi r

Therefore:

2\pi r =18\pi $ meters\\2r=18\\r=18 \div 2\\$Radius, r=9 meters

Area of a Circle =\pi r^2

Since radius of the cross section of the column =9 meters

Area of the cross section of the column

=\pi *9^2\\=81\pi $ m^2

Azmyne decided to spend 6 1/2 hours studying over the weekend. She spent 1 1/4 hours studying on Friday evening and 2 2/3 hours
nata0808 [166]

Answer: 2\ \dfrac{7}{12}\ \text{hours}

Step-by-step explanation:

Given

Azmyne decided to study a total of 6\ \frac{1}{2}\ hours

She spent 1\ \frac{1}{4}\ hours on Friday and  2\ \frac{2}{3}\ hours on Saturday

Hours spent on Friday

\Rightarrow 1\ \frac{1}{4}=\frac{5}{4}\ hours

Hours spent on Saturday

\Rightarrow 2\ \frac{2}{3}=\frac{8}{3}\ hours

She must study for

\Rightarrow \dfrac{13}{2}-\dfrac{5}{4}-\dfrac{8}{3}\\\\\Rightarrow \dfrac{13\times6-5\times3-8\times4}{12}=\dfrac{78-15-32}{12}\\\\\Rightarrow \dfrac{31}{12}=2\ \frac{7}{12}\ \text{hours}
