Answer: 
Step-by-step explanation:
You need to analize the information given in the exercise.
By definition, there are 360 degrees in a circle.
In this case, you know that the Central angle in degrees of the given sector of the circle is the following:
And the area of that sector is this one:
Then, you need to calculate the number of sectors in that circle.
In order to do it, you have to divide 360 degrees by the central angle of that sector. So, you get:
Knowing that there are 8 sectors in the circle, you need to multiply the area of the sector given in the exercise by 8, in order to calculate the area of the circle.
Therefore, this is (Using 
):

Answer:
22m
Step-by-step explanation:
The computation is shown below:
Since it is a right-triangular garden so we use the pythagoreus theorem
As we know that
The C^2 refers to the longest side of the right-triangular garden
So,
a^2 + b^2 = c^2
a^2 + 14^2 = 26^2
a^2 + 196 = 676
a^2 = 480
So a = 22m
Hence, the other side of the garden is 22m
3 shifts*8 hours each= 24 hours worked
$240/24 hours= $10 per hr
Final answer: $10 per hr
There are 187 nickels and 66 dimes in the jar.
Step-by-step explanation:
Given,
Total coins = 253
Value of coins = $15.95 = 15.95*100 = 1595 cents
Value of each nickel = 5 cents
Value of each dime = 10 cents
According to given statement;
x+y=253 Eqn 1
5x+10y=1595 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 5
Putting y=66 in Eqn 1
There are 187 nickels and 66 dimes in the jar.
