He added 8 to both sides. He did the write thing.
The area of the square is 9, the area of all the semi circles added together is 15.7, when you add them together you get 24.7
Answer:
From the above we can roughly for an equation which is:
58.50 = Bill - (10% x Bill)
58.5 = Bill - (1/10 x Bill)
58.5 = 9/10 x Bill (Divide both sides by 9/10)
We get:
Bill = 58.5 / (9/10)
Bill = 65
Original bill is $65.
<h3>SOLUTION : </h3>
The radius of the circle is 4 inch and has an arc length of 5.8 inches . We know that if the central angle is 360° then the arc length is 
. Similarly when angle is theta ,
Now substitute respective values , from the given data ,
This is our required answer!
Answer:
F = 25
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2
Here V = 11, E = 34, thus
F + 11 - 34 = 2
F - 23 = 2 ( add 23 to both sides )
F = 25
