Answer:

1) 12/19 - 1/2 = 5/38

2) 5/7 + 3/8 = 1 5/56

Step-by-step explanation:

12/19 - 1/2

= (12 * 2 - 19 * 1) / 19 * 2

= (24 - 19) / 38

= 5/38 ---> answer

5/7 + 3/8

= (5 * 8 + 7 * 3) / 7 * 8

= (40 + 21) / 56

= 61/56 ----> now, convert to mixed fraction

= 1 5/56 ---> answer

What is the area of a sector with a central angle of (2pi/3) radians and a diameter of 12 in?

Stels [109]

Answer:

The area of the sector is $37.68\ in^{2}$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=12/2=6\ in$ ----> the radius is half the diameter

substitute

$A=(3.14)(6)^{2}$

$A=113.04\ in^{2}$

step 2

Find the area of a sector with a central angle of (2pi/3)

Remember that

The area of $113.04\ in^{2}$ subtends a central angle of $2\pi \ radians$

by proportion

Let

x----> the area of the sector

$\frac{2\pi}{113.04}=\frac{(2\pi/3)}{x}\\ \\x=113.04*(2\pi/3)/(2\pi)\\ \\x=37.68\ in^{2}$
