A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.
Area of a circle: A = pi x r^2
r = 160 / 2 = 80
A = pi x 80^2
A = 6400pi / 2 = 3200pi
3200pi = 10053.0965
The area water is approximately 10,053 ft^2.

Answer:
Same speed.
Step-by-step explanation:
divide Distance by speed
25.5/3=8.5mph
34/4=8.5mph
Answer:
The answer to this question would be (to my best guess), 36 hours.
Step-by-step explanation:
First
You have to find the ratio between 87.5% and 100%. This is because you want to find what 100% represents.
To do this, you have to divide 100 by 87.5, which would represent 100 divided by 87.5. This will equal 1.142857142857143 , which isnt an easy number to work with.
Lastly
You have to multiply 1.142857142857143 by 31.5, because you reverse the previous operation, but the only difference is you swap out the percentages with the numbers they represent. This equals the final answer, which is 36, representing 36 hours.
Answer:
It’s rotation 180 degrees about the origin.

Answer: 

Step-by-step explanation:
Given : P(A)=0.60 and P(B)=0.30
We will say A and B are independent events if :


Thus , A and B are independent events if :
