C = 2×pi×r
72 = 2×pi×r

so r = 36/pi

DE = 30deg×36/pi
DE = (pi/6)×(36/pi) = 6cm

Summy is working in geometry class and is given figure abcd in the coordinate plane to reflect the coordinates of point d are a

fgiga [73]

Answer:

Answer is B

Step-by-step explanation:

If point D with coordinates (a,b) is reflected over the line y=x then the image point D' coordinates are (b,a) (see picture for details).

The middlepoint M of segment DD' lhas coordinates and lies on the line y=x (since its coordinates are equal), DD' is perpendicular to the line y=x and DM=D'M. All these remarks show that the point D' is the image point of D.

jeka94

Answer:

The greatest common factor of 36 and 54 is 18.

Step-by-step explanation:

To solve this problem, first, you have to find the greatest common factor (GCF) of 36 and 54.

Factors of 36:

1, 2, 3, 4, 6, 9, 12, 18, and 36.

Factors of 54:

1, 2, 3, 6, 9, 18, 27, and 54.
