How many decimal places do you need to move the decimal to the left to write the below in specific notation?

The ray EG is the angle bisector of DEF and m DEF = 84º. Find mDEG. mDEG = degrees

SVEN [57.7K]

42 degrees. Since the Ray is the angle bisector, that means it divides angle DEF into two angles with equal measure. So, divide 84 by 2 to get 42.

A semi-circle window can be used above a doorway or as an accent window

anzhelika [568]

A semicircle is a part of a circle, and it is referred to as half of a given circle. Thud the area of the semi-circle window is 982 $in^{2}$ .

A circle is a shape that is bounded by a curved path which is referred to as the circumference. Some parts of a circle are radius, diameter, sector, arc, semi-circle, circumference, etc.

A semicircle is a part of a circle, and it is referred to as half of a given circle.

such that:

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

and

area of a semicircle = $\frac{\pi r^{2} }{2}$

where: r is the radius of the circle, and $\pi$ is a constant with a value of $\frac{22}{7}$ .

Thus from the given question, it can be inferred that;

r = $\frac{50}{2}$

= 25

r = 25 in

Thus, the area of the semi-circle can be determined as;

area of the semi-circle = $\frac{1}{2}$ * $\frac{22}{7}$ * $25^{2}$

= 982.1429

area of the semi-circle = 982.14 $in^{2}$

The area of the semi-circle window is approximately 982 $in^{2}$ .
