Using the formula c=2×n×r find the circumference of a circle of radius 5cm (n=3.14)

The answer is 31.4 just do 3.14 times 5 times 2

Substitute the information into the formula

C= 2 x 5 x 3.14
C= 10 x 3.14
C=31.4

Hope this helps

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
