#1). The length of the whole circumference is (π · D) = 12π .

   120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.

#2). 60° is 1/6 of 360°.
   So arc-CD is 1/6 of the whole circumference (which is given).

#3). The circumference of the circle is (π·D) = 20π .

   70° is (70°/360°) of the whole circle, so arc-XY
   is (70/360) of the whole circumference.

#4). Sorry, I don't remember anything right now about
   angles between chords.
   I hope what I've given you so far is worth 5 points.

2.80=9(70)/I. I need a answer for i

Westkost [7]

I would be 225 since 9(70) is 630 and since you are solving for I, you multiply both sides by i and divide by 2.80

What are two rational numbers between -3/4 and -2/3

Vadim26 [7]

The two rational numbers between $- \frac{3}{4}$ and $- \frac{2}{3}$ is $- \frac{32}{48}$ , $- \frac{36}{48}$

<h3>How to find the rational numbers between -3/4 and -2/3?</h3>

In the form of p/q, which can be any integer and where q is not equal to 0, is expressed as rational numbers. As a result, rational numbers also contain decimals, whole numbers, integers, and fractions of integers (terminating decimals and recurring decimals).

given that -3/4 and -2/3

now take L.C.M between these two rational numbers is 12.

now multiply -3/4 with 3 both numerator and denominator

$- \frac{3}{4} \times \frac{3}{3} = - \frac{ 9}{12}$
