<h3>Answer:</h3>
[C] 3 + ( - 4).
<h3>Explanation:</h3>- First the arrow begins at 0 and moves to the right 3 spaces positive, ending at 3.
- Then it moves backwards, which is subtracting left 4 spaces towards -1 past zero.
- When adding a negative to a positive, you convert it to subtraction.
- 3 + -4 is the same as 3 - 4.
<u>Correct choice</u> - [C] 3 + (- 4).
<u>Note</u>: See the picture attached.
A semicircle is a part of a circle, and it is referred to as half of a given circle. Thud the area of the <em>semi-circle</em> window is 982 .
A circle is a shape that is <u>bounded</u> by a <em>curved</em> path which is referred to as the <em>circumference</em>. Some <u>parts</u> of a circle are radius, diameter, sector, arc, semi-circle, circumference, etc.
A <em>semicircle</em> is a <u>part</u> of a <u>circle</u>, and it is referred to as <em>half </em>of a given <em>circle</em>.
such that:
<em>Area</em> of a <u>circle</u> =
and
area of a <u>semicircle</u> =
where: r is the <u>radius </u>of the <u>circle</u>, and is a <u>constant </u>with a value of
.
Thus from the given question, it can be inferred that;
r =
= 25
r = 25 in
Thus, the area of the<em> semi-circle</em> can be determined as;
area of the <em>semi-circle</em> = *
*
= 982.1429
area of the semi-circle = 982.14
The area of the <em>semi-circle</em> window is approximately 982 .
