Answer:

344 {cm}^{2}

Step-by-step explanation:

area \: of \: the \: square \\  = 40cm \times 40cm \\  = 1600 {cm}^{3}  \\

area \: of \: the \: circle \\  = \pi {r}^{2}  \\  = 3.14 \times  {(20)}^{2}  \\  = 3.14 \times 400 \\  = 1256 {cm}^{2}  \\

area \: of \: shaded \: region \\  = 1600 {cm}^{2}  - 1256 {cm}^{2}  \\  = 344 {cm}^{2}  \\

Which statement is true of triangles P and Q? Triangle P has side lengths of 6, 8, 10 and angle measures of 53.1 degrees, 90 deg
Wewaii [24]

Answer:

Triangle P and Triangle Q are mathematically similar shapes (?).

Step-by-step explanation:

Hi, so the question asks which statement is true, given the following information, but you haven't written what statements we can choose from.

After reading the information, we can see that Triangle Q is the same shape as Triangle P but just larger.

I'm assuming that one of the statements given is about Triangle P and Triangle Q being mathematically similar shapes?

If you need to show your working out, here it is:

18 ÷ 6 = 3

24 ÷ 8 = 3

30 ÷ 10 = 3

All the angles are the same.

This means that the length scale factor is +3 from Triangle P to Triangle Q, the area scale factor is +9 (because 3 x 3 = 9) from Triangle P to Triangle Q, and that the two shapes are mathematically similar.

*DISCLAIMER* The majority of question askers on Brainly seem to be from the US, and I'm not, so the way I work things out / the mathematical terms I use might be different. Sorry!

Hope this helped anyway!
