Note:
The area of a circle with radius r is πr².
An entire circle has a central angle of 360°.

For the sector with radius = (3+4) = 7cm and a central angle of 120°, the area is
A_{1}= \frac{120}{360}*(49 \pi ) = \frac{49}{3} \pi \, cm^{2}

For the sector with radius =  3 cm and a central angle of 120°. the area is
A_{2}= \frac{120}{360} *(9 \pi ) = 3 \pi  \, cm^{2}

The area of the shaded sector (see the figure) is
A=A_{1}-A_{2} = ( \frac{49}{3} -3) \pi  =  \frac{40}{3} \pi  \, cm^{2}

Answer: \frac{40}{3}  \pi  \, cm^{2}

What is the fraction is less than 5/6 and has denominator of 8?
IrinaVladis [17]

Denominator is the number which appears at the bottom of fraction so the fraction we want is in the form X/8 and also less than 5/6

Lets start from changing the values of X from 1.

1/8 = 0.125 and 5/6 = 0.8333

2/8 = 0.25

3/8 = 0.375

4/8 = 0.5

5/8 = 0.625

6/8 = 0.75

7/8 = 0.875, this is greater than 5/6

<span>So, the fractions with denominator 8 and less than 5/6 are 1/8, 2/8, 3/8, 4/8, 5/8 and 6/8</span>
