Answer: 50.24 cm^2
Step-by-step explanation:
This can be translated to:
An old coin is kept in a cubic box in such a way that the outline of the coin touches the 4 walls of the box, if the base of the box has a perimeter of 24 cm. What is the area of the coin?
The fact that the coin touches the interior of the box means that the diameter of the coin is equal to the side lenght of the box.
The perimeter of the box is 24 cm, and the perimeter of a square is equal to:
P = 4*L
where L is the side lenght of the square.
24 cm = 4*L
L = 24cm/4 = 8cm
Now we know that the diameter of the coin is 8cm
Now, the area of a circle (the coin) is equal to:
A = 3.14*(d/2)^2
where d is the diameter, so we have:
A = 3.14*(4cm)^2 = 50.24 cm^2

Answer:
Step-by-step explanation:
Hey there!
so answer for (A is 1)
Answer for (B is 100)
Thank you have fun!
-1/3 m - 7 = 5
add 7 to each side
-1/3 m = 12
multiply by -3 to each side
m = -36
I think its perimeter so you do 10x2=20 and 20x2=40 and add 20+40 to get 60 so the answer is 60 cause it says "fencing" which is the outer border
therefore answer is 60 feet
