<span>The formula is simply this: C = πd where C is the circumference, pi is equal to 3.1416 and d is the diameter which equal to twice the radius. We use this equation to calculate for radius. We do as follows:
</span>
C = πd
36π = πd
d = 36

d = 2r
36 = 2r
r = 18 cm <--------OPTION A

Answer:

In short, they are all quadrilaterals.

Step-by-step explanation:

<u>Rectangle:</u>

- Every angle equals 90 degrees

- Opposite sides are equal and parallel

<u>Square:</u>

- Every angle equals 90 degrees

- Opposite sides are equal and parallel

- Diagonals within the square are perpendicular

<u>Parallelogram:</u>

- Opposite sides are equal and parallel

- Opposite angles are equal

- Any two angles next to each other have to equal 180 degrees, since it would be a line

<u>Rhombus:</u>

- Opposite angles are equal

- All sides are equal

- Opposite sides are parallel

- Diagonals within the square are perpendicular

- Any two angles next to each other have to equal 180 degrees, since it would be a line

<u>Trapedzoid:</u>

- There is only one pair of parallel lines

<u>Kite:</u>

- There are two pairs of equal signs

- There are two equal angles

- You can look at it like two equal triangles glued together

Really hope this helped you!

Answer:

2 7/24C

Step-by-step explanation:

Start by finding the common denominator. In this case, it's 24. Next, start translation.

2/3C = 16/24C

7/8C = 21/24C

3/4C = 18/24C

Then find the sum.

16/24C + 21/24C + 18/24C = 55/24C = 2 7/24C
