If the diameter is 1 what is the radius, circumference, and the area

The radius would be .5.

When the diameter of a circle is 1, the circle's circumference is equal to pi. 

The area would be .79

I hope this helped you!

Brainliest answer is always appreciated!

Well the radius is half the diameter so the radius is .5, the circumference is 2(pi)r or (pi)d, so it would be 3.141592654... Now finally the area it is (pi)r^2 so it would be about .79.

Radius=.5
Circumference= 3.14
Area=.79

This does not make sense

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
