Diameter=side

find area of field (square) and area of sprinkler (circle)


ara of square=side^2
area of circle=pir^2

area of square=12^2=144

area of circle=pir^2
d/2=r
12/2=6=r
area=pi6^2
area=36pi
aprox pi=3.14
area=113.04


area wasted=area of field-arrea of sprinlker
area wasted=144-113.04=30.96 m^2

1 0-2 4

2 3 -4 1

3 5-6 2

4 7-8 2

5 9 - 10 0

6 11 - 12 0

The value for value upper class boundary of the fifth class is CB_5 =  10.5

Step-by-step explanation:

From the question we are told that

The lower class limit is 0

The class width is 2

The scores is 8,6,2,4,2,0,2,6,7

The frequency distribution is

S/N Class limit Frequency

1 0-2 4

2 3 -4 1

3 5-6 2

4 7-8 2

5 9 - 10 0

6 11 - 12 0

Generally the upper class boundary of the fifth class is mathematically represented as

CB_5 =  \frac{10 + 11}{2}
