Answer:
Option C) 113.0 feet squared
Step-by-step explanation:
We are given the following in the question:
Radius of circular garden = 4 feet
Length of path around garden = 2 feet
We have to find the total area of garden and path.
The garden and path together makes a bigger circle with radius
Area of garden and path =
Putting values, we get,
Thus, the correct answer is
Option C) 113.0 feet squared
A = 81 square in.
s = sqrt(A)
s = sqrt(81)
s = 9 in.
The answer would be 11 gallons.
The tub starts with 32 gallons. Every minute it loses 3 gallons.
So after 1 minute it has lost 3 gallons. For example:
32-3= 29 Meaning that after 1 minute the tub has 29 gallons left.
Now you have to remember that the tub is draining for 7 minutes. So it is losing 3 gallons 7 times, because it loses 3 gallons each minute and there are 7 minutes.
We can use multiplication to find how many gallons the tub loses after 7 minutes. This sign “X” basically means “groups of”. We have 7 groups of 3, or
7 X 3
This is the same as saying we have 3, 7 times. Written like this:
3+3 +3 +3 +3 +3 +3 = 21
So after 7 minutes the tub has lost 21 gallons.
Now we take the original number of gallons and take away what was lost:
32-21=11
So there are 11 gallons left after 7 minutes.
Please let me know if you need any further explanation. Hope this helped.
