The measurement of the circumference of a circle is 21.3 ft.
What is Circumference of Circle?The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
Here, given area of circle = 36 ft²
Area of Circle = πr²
36 = 3.14 X r²
r² = 11.46
r = 3.38 ft.
Circumference of Circle = 2πr
= 2 X 3.14 X 3.38
= 21.25 ft. ≈ 21.3 feet
Thus, the measurement of the circumference of a circle is 21.3 ft.

I NEED MEGA HELP WITH THIS QUESTION
Answer:
C. [tex]y = - \frac{1}{4} x - 2[/tex]
Step-by-step explanation:
To find slope using coordinates, use the formula above.
[tex](4, - 3) \: (0, - 2)→ \frac{ - 2 - ( - 3)}{0 - 4}→ \frac{ - 2 + 3}{ - 4} → - \frac{1}{4} [/tex]
Now, using the [tex]y = mx + b[/tex] formula, plug in [tex] - \frac{1}{4} [/tex] as [tex]m[/tex] (slope) and either coordinate as the [tex]x[/tex] and [tex]y[/tex] values. It looks like this:
[tex] - 3 = - \frac{1}{4}(4) + b[/tex]
To solve for [tex]b[/tex], continue to use PEMDAS.
[tex] - 3 = - \frac{1}{4}(4) + b→ - 3 = - 1 + b→ - 2 = b[/tex]
Now use [tex]m[/tex] and [tex]b[/tex] to solve for your equation:
[tex]y = - \frac{1}{4} x - 2[/tex]
The answer is C.

Imagine making slices through the solid parallel to the bases. What two-dimensional shapes are formed
Answer:
shape as that of the base of the solid
Step-by-step explanation:
A solid has a three dimensional shape. A three dimensional shape has both length, breadth and height. If the solid is being cut parallel to the base, a two dimensional shape (has length and width) is formed.
The shape of the two dimensional shape is the same as the shape of the base. Hence if solid is cut parallel to the bases, the shape formed would have the same shape as that of the solid base.

Answer:
C. {-9,-3}
Step-by-step explanation:
[tex]|k+6|=3[/tex] gives [tex]k+6=3[/tex] if [tex]k + 6 \geq 0[/tex]. This gives [tex]k=-3[/tex], which is valid.
It can also give [tex]-(k+6) = 3[/tex] if [tex]k + 6 < 0[/tex]. This gives [tex]k=-9[/tex], which is valid.
Hence the solutions are [tex]k=-9 \vee k=-3[/tex].
James paid an initial fee of $6.00 for a movie rental service. Each time he rents a movie he is charged $2.00. Sarah uses a different movie
rental service that charges based on the equation y = 3x + 4, where y is the total cost and x is the number of movies rented. At what point
are the prices of the two services the same?
606
Answer:
We have system of equations
James's total cost: Y = 2x + 6 (1)
Sarah's total cost: Y = 3x + 4 (2)
replace y = 2x + 6 and (2) => 2x + 6 = 3x + 4 => x = 2 => y = 10
So the total cost of renting movies by James And Sarah is equal
