The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle with diameter of 38 cm.

Diameter = 38 cm

The radius of the circle = 38/2 = 19 cm

Perimeter of the circle = 2πr = 2π(19) = 38π cm

Perimeter of the semicircle = 38π/2 = 19π cm

Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

Pls help, I don’t understand how to do this

MAVERICK [17]

Answer:

5 parts are shaded and 4 parts are white so:

There are 9 parts all together.

We can then form ratio's of the white areas and the shaded areas:

White Area Ratio =

$\frac{4}{9}$

Shaded Area Ratio =

$\frac{5}{9}$

Let the area of sqaure be equated to x, which means let the entire area of the square equal to x:

x = Area of whole square

Now we can form an equation :

$\frac{5}{9} x = 165$

So now we just need to solve for x:

$x = \frac{165}{ \frac{5}{9} }$

$x = 297$

The area of the square is:

$297 {cm}^{2}$
