The area of yard gets watered is 707.142 ft²
What is area?
The portion between any closed figure, and the extent of region of any plane is area.
Given that sprinkler sprays 15 feet in every direction
so it will form a circle with radius of 15ft
and area of circle is πr²
where r is radius of circle
value of π is 22/7
area = π x (15)²
area = 707.142 ft²
Hence area of sprinkled region is 707.142 ft²

To evaluate for P(0.372<x<0.428) we shall proceed as follows:
z-score is given by:
z=(x-μ)/σ
thus when x=0.372:
z=(0.372-0.4)/0.028
z=-1
thus
P(x<0.372)=P(z<-1)=0.1587
when x=0.428
z=(0.428-0.4)/(0.028)=1
P(x<0.428)=P(z<1)=0.8413
thus
P(0.372<x<0.428) =P(z<1)-P(z<-1)=0.8413-0.1587=0.6826
Final answer:
To find the percentage of observations between two values in a normal distribution, we can convert the values to z-scores and use a z-table to find the corresponding areas. In this case, the percentage of observations between 0.372 and 0.428 is 68.26%.
Explanation:
To find the percentage of observations that will lie between 0.372 and 0.428 in a normal distribution with a mean of 0.40 and standard deviation of 0.028, we need to find the area under the curve between these two values.
Using a standard normal distribution table or z-table, we can convert the values to z-scores by subtracting the mean and dividing by the standard deviation. The z-score for 0.372 is (0.372 - 0.40) / 0.028 = -1, and the z-score for 0.428 is (0.428 - 0.40) / 0.028 = 1.
By looking up the corresponding area for these z-scores in the z-table, we find that the area to the left of -1 is 0.1587 and the area to the left of 1 is 0.8413. To find the percentage between -1 and 1, we subtract the smaller area from the larger area: 0.8413 - 0.1587 = 0.6826 or 68.26%.

Answers
Answer:
i = 1000cm2
ii = 100000cm3
Step-by-step explanation:
for q i
surface area of base = l* b
= 50* 20
1000cm^2
for q 2
volume l*b*h
= 50*20*10
= 100000cm^3
