Answer with Step-by-step explanation:

The perimeter(P) of a semi circle is given by:

P=πr+2r

where r is the radius of the semicircle

r=d/2 where d is the diameter

We are given diameter=12 cm

⇒ Radius= 12/2

= 6 cm

Perimeter=3.14×6+2×6

=18.84+12

=30.84 cm

Hence, best approximation for the perimeter of a semicircle with a diameter of 12 cm is:

30.84 cm

In which quadrant does point W(-3,-9) lie

Marat540 [252]

Answer:

<h2>D. Quadrant III</h2>

Step-by-step explanation:

Quadrant in coordinate geometry is divided into four parts which is called Quadrants.

Quadrants I (x, y)

Quadrants II (-x, y)

Quadrants III (-x, -y)

Quadrants IV (x, -y)

so W(-3, -9) both are negatives so its lie on Quadrants III
