What is the minimum angle of rotation (in degrees) that will carry the star onto itself?

zloy xaker [14]

Answer:

When you rotate the regular pentagon \begin{align*}72^\circ\end{align*} about its center, it will look exactly the same. This is because the regular pentagon has rotation symmetry, and \begin{align*}72^\circ\end{align*} is the minimum number of degrees you can rotate the pentagon in order to carry it onto itself.

What is the perimeter of this figure, to the nearest unit?

lana66690 [7]

Answer:

P=38

Step-by-step explanation:

At this case I would use the circumference formula for the rounded part.

The formula of the circumference is C=2πr.

So... We know that the radius is 5 which is half of the diameter. So... C=2π5 which is C=10π or C=31.4 which we divide by 4 because on the image is 1/4th of a circle and C/4 which C=7.85 so the P of the whole figure is P=10+10+5+5+7.85 which is P=37.85 which will be P=38.

Answer: P=38
