Step-by-step explanation:

Area of the blue shaded region

=  \frac{ \theta}{360 \degree}  \times \pi r_1^2  - \frac{ \theta}{360 \degree}  \times \pi r_2^2  \\  \\  =   \frac{ \pi\theta}{360 \degree} ( r_1^2 - r_2^2) \\  \\ ( r_1 = 4 \: cm, \:  \:  r_2 = 3\: cm, \:  \:  \theta = 120 \degree) \\  \\ =   \frac{ 3.14 \times 120 \degree}{360 \degree} ( 4^2 - 3^2) \\  \\  =   \frac{ 3.14 }{3}  \times 7 \\  \\  =  \frac{21.98}{3}  \\  \\  = 7.32666667 \\  \\  \approx \: 7.33 \:  {cm}^{2}

12 1/2 subtract 5 3/8
White raven [17]

Answer: 7 and 1/8

Step-by-step explanation: To subtract mixed numbers such as 8 and 5/16 - 5 and 3/8, we first subtract the fractions.

Notice that 1/2 and 3/8 are unlike fractions so we need a common denominator, which in this case is 8.

Since 1/2 does not have 8 in the denominator, we multiply the numerator and denominator of 1/2 by 4 and we get the equivalent fraction 4/8.

Now we have 12 and 4/8 - 5 and 3/8.

Now, subtract the fractions. So we have 4/8 - 3/8 which is 1/8. Then we subtract the whole numbers. 12 - 5 is 7 so we have 7 and 1/8 as our answer.

Therefore, 12 and 1/2 - 5 and 3/8 is 7 and 1/8.
