a table is 60 cm in diameter. A tablecloth hangs 65cm all around. how much lace trim is needed to edge the cloth
1 answer:
The circumference of a circle is the <em>total length</em> of the <u>boundary</u> of the circle. So that the length of lace trim required is 597.1429 cm.
The <em>diameter</em> of the table is <u>60</u> cm, which has <u>65</u> cm tablecloth hanging on its sides. The diameter of the cloth required would be the <em>length</em> from <u>one</u> side to the <u>other</u> side. So that the <u>total</u> diameter of the tablecloth is:
= 60 cm + 2*65 cm
= 60 cm + 130 cm
= 190 cm
The <em>diameter</em> of the <u>tablecloth</u> required is 190 cm.
Thus to determine the <em>circumference</em> of the <u>tablecloth</u>, we have;
C = 2r
= D
where D is the <u>diameter</u> of the tablecloth.
C = x 190
= 597.1429
C = 597.1429 cm
Therefore, the length of lace trim required for the <em>edge</em> of the <u>tablecloth</u> is 597.1429 cm.

Answer: SECOND OPTION.
Step-by-step explanation:
It is important to remember that, by definition, the "Resultant vector " is the vector obtained by adding two or more vectors.
For this exercise you need to use the formula for calculate the magnitude of the resultant vector obtained by adding the vectors "a" and "b" shown in the picture attached:
Where "c" is the magnitude of the resultant vector asked in the exercise.
You need to analyze the graph given in the exercise.
You can identify that:
Then the next step, knowing which are "a" and "b", is to substitute values into the formula given at the beginning of this explanation, as following:
Finally, evaluating, you get that "c" is:
