In a class, everyone studies French or German, but not both languages. One third of the girls and the same number of boys study German. Twice as many boys as girls study French. Which of the total number of boys and girls in my class
Answer:
32
Step-by-step explanation:
Let the number of girls in the class be 3. Then the number of girls who study German is , as is
the number of boys who study German. So the number of girls who study French is 2 and the
number of boys who study French is 2 × 2 = 4.
Therefore the total number of boys and girls in the class is + + 2 + 4 = 8 and hence is a
multiple of 8. Of the options, only 32 is divisible by 8.

The area of a sector of a given circle is 37.7 m².
Given that, the radius of a circle=4 m and the central angle of a circle=270°.
What is the formula to find the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector is θ/360°(πr²).
Where r is the radius of the circle and θ is the angle of the sector.
Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².
Therefore, the area of a sector of a given circle is 37.7 m².
