Find the area of a circle with a circumference of 18.84 units

278.773622 or 300 if rounded

Step-by-step explanation:

The area of a circle is:

π (Pi) times the Radius squared:

A = π r2

or, when you know the Diameter:

A = (π/4) × D2

or, when you know the Circumference:

A = C2 / 4π

it would be:

c.parallelogram.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
