Answer:

Circumference of a circle= 2\pi r

Step-by-step explanation:

The circumference of any circle is the total length of its boundary which can be calculated by the formula:

                Circumference of a circle= 2\pi r

               Where 'r' is the radius of the circle

For, the given circle the circumference can be find in terms of \pi  by putting some value of radius in the formula, which gives the circumference in terms of \pi.

What is the smallest degree of rotation that will map a regular 18-gon onto itself?
Korolek [52]
Because the 18-gon is symmetrical, you can rotate it by 360/18 or 20 degrees. This is because when you rotate it by 20 degrees(to the left for explanation matters), any angle will now be in the position of its angle to its left.

Katrina wants to build a fence around her Square Garden the garden has an area of 121 square feet How much Fencing will Katrina
Sindrei [870]

Answer:

<em>The perimeter of the fencing is 44 feet (Option D)</em>

Step-by-step explanation:

<u>Area and Perimeter</u>

A square shape of side length (a) has an area given by:

A = a^2

And its perimeter is calculated as:

P = 4a

The area of Katrina's square garden is given as A=121 square feet. We need to calculate the side length by solving for a:

a=\sqrt{121}

a = 11 feet

Once we know the value of a, then we calculate the perimeter:

P = 4*11 = 44

The perimeter of the fencing is 44 feet (Option D)

What is negative 8 over 12?
Sedaia [141]
That would be \frac{-8}{12}, but it is also equal to just -\frac{8}{12}. You would simplify the \frac{8}{12} part, and you would get \frac{2}{3}, or if you need a decimal, 0.6666...
But don't forget the negative part, so the answer would be -\frac{2}{3} or -0.6666...
