Why is adding 3/9 and 6/9 different from multiplying the two fractions?

Mathematics

First off 3/9 and 6/9 are already common denominators. In some fractions you would need to find the least common denominator like in a problem like 1/2 + 4/5. Also 3/9 plus 6/9 results in 9/9 and 9/9 equals 1. Most fractions adding it subtracting results in a pan answer as a fraction but in this case it’s a whole number.

Answer:

Second option is correct

Arc\ length = \frac{3}{4} \pi\ in

Step-by-step explanation:

Given:

Central angle = 15°

Radius of the circle = 9 in

Arc length = ?

Given formula is

\frac{Arc\ length}{Circumfrance} = \frac{n}{360}

Where n is the central angle of the sector.

Write the given formula for Arc length of the sector.

Arc\ length = Circumfrance\times \frac{n}{360}

We know that the the circumference of the circle is 2\pi r, where r is the radius of the circle,

Arc\ length = 2\pi r\times \frac{n}{360}

Now we substitute central angle value and radius value in above equation.

Arc\ length = 2\pi 9\times \frac{15}{360}

Arc\ length = 18\times \pi \frac{15}{360}

Arc\ length = \frac{18\times 15}{360} \pi               ----------(\frac{18}{360}=\frac{1}{20})

Arc\ length = \frac{15}{20} \pi

Divide the numerator and denominator by 5.

Arc\ length = \frac{3}{4} \pi\ in

Therefore the arc length of the sector is \frac{3}{4} \pi\ in
