Answer:
12:30 pm
Step-by-step explanation:
8:30 am pond is empty
10:30 am pound is 1,400 gallons full
   time?    pound is 2,800 gallons full
from 8:30 to 10:30 are 2 hours so the rate of filling up is 
              1,400 gallons in 2 hours 
to have a whole pond filled we need another 2 hours because 
in another 2 hours will have another 1,400 gallons so a pound full. 8:30 am + 2hours = 12:30 pm
8:30 am pond is empty
10:30 am pound is 1,400 gallons full
12:30 pm pound is 2,800 gallons full.
 
        
             
        
        
        
Answer:
(x-2)^2 + (y-3)^2 = 4
Step-by-step explanation:
Use the equation (x-h)^2 + (y-k)^2 = r^2 where the center of the circle is (h,k) and the radius is r.
 
        
             
        
        
        
Answer:
The measurement of the central angle AOB is 45 degrees
Step-by-step explanation:
To solve this problem, we will have to work with fractions.
We will get the fraction of area the shaded portion is when compared to the whole garden.
First of all, we will need to calculate the area of the garden which is 
in this case, our radius is 8 inches.
Next, we will compare the area of the sector to the area of the garden. This will be
This will be the shaded area/ area of the whole garden
= 

We will now convert this ratio to an angle by multiplying it by 360 degrees.
This will be:

The measurement of the central angle AOB is 45 degrees
