Answer:
0.2146
Step-by-step explanation:
From the picture:
The radius of the circle = r. This means that the area of the circle = πr²
Also For the square, the length of the square = 2r, Therefore the area of the square = Length × length = 2r × 2r = 4r²
The area inside the square but outside the circle = Area of square - Area of circle = 4r² - πr² = r²(4 - π) = 0.8584r²
The ratio of the area inside the square but outside the circle to the area of the square = r²(4 - π) / 4r² = (4 - π) / 4 = 1 - π/4 = 0.2146
Answer:
The class 35 - 40 has maximum frequency. So, it is the modal class.
From the given data,
MODE
- Most precisely, mode is that value of the variable at which the concentration of the data is maximum.
MODAL CLASS
- In a frequency distribution the class having maximum frequency is called the modal class.
