Answer:

Area of circle is 221.56 units ² .

Step-by-step explanation:

Formula

Area\ of\ circle = \pi r^{2}

Where r is the radius of the circle.

As given

The diameter of a circle is 16.8 unit.

Radius = \frac{Diameter}{2}

Radius = \frac{16.8}{2}

Radius = 8.4 units

\pi = 3.14

Putting all the values in the formula

Area\ of\ circle = 3.14\times 8.4\times 8.4

                                = 221.56 units² (Approx)

Therefore the area of circle is 221.56 units ² .

221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared. 

In this case, area = (3.14 / 4) x (16.8 x 16.8)

Basically, take the union of both domains g(x)=x/(1-x) 1-x=0 1=x x=1 is restricted because it makes you divide by 0 f(x)=(1-x)/(1+x) 1+x=0 x=-1 x=-1 is restricted because it makes you divide by 0 domain is all real numbers except -1 and 1

Jillian is making curtains for her room. She has fabric for each curtain that is 1.6 meters in length. She folds the bottom of t
iogann1982 [59]
The curtains will be 152 cm or 1.52 m.

There are 100 cm in a meter. Therefore, 1.6 meters is equal to 160 cm. If we subtract 8 from 160, we have 152 cm. We can also write it as 1.52 m.
