The area of the sector (As) of a circle may be calculated by the formula,
                                     As = (a / 360) x π x r²
where a is the measure of angle in degrees and r is the radius. Substituting the known values, 
                                    As = (18 / 360) x 3.14 x (4²) = 2.512
Thus, the area of the sector is approximately 2.512 squared units.

Area of a sector;
A=\frac{∅}{360}  \pi  r^{2}
A=\frac{18}{360} *3.14* 4^{2}
A=2.512 square units.

What numbers are a distance of 4\6 unit from 3\6 on a number line?<br><br>Please help me out.
sweet [91]

The numbers that are a distance of 4/6 unit from 3/6 on a number line are -1/6 and 7/6

<h3>What is the distance on a Number Line?</h3>

We want to know what numbers are a distance of 4/6 unit from 3/6 on a number line.

Add 4/6 to 3/6, and also subtract 4/6 from 3/6. That will give the two numbers.

3/6 + 4/6 = 3/6 + 4/6 = 7/6

3/6 - 4/6 = -1/6

Thus, the numbers that are a distance of 4/6 unit from 3/6 on a number line are -1/6 and 7/6

timama [110]

Answer:

2/10

Step-by-step explanation:

Probability of getting head on i'th coin = i/10

Probability Pr of getting head on 2nd coin (Event A) = 2 / 10

Probability Pr of getting head on 1st coin (Event B) = 1/10

Probability A given B = Pr (A/B) = Pr (A∩B) / Pr B ;

where A∩B = Pr (A & B) = Pr A X Pr B

Putting in above formula :

Pr (A/B) = <u>[(</u>1/10)x(2/10<u>)]</u>  / 1/10

= 2/10
