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 1: 10 group(s) of 23=230
Step 2: 6 group(s) of 23=138
Step 3: Add the partial quotients: 10 + 6 = 16
Step-by-step explanation:
For this case we have an equation of the form:
Where,
A: original price
b: growth rate
x: number of years
Substituting values we have:
Answer:
the value of the antique clock, and, in dollars, after x years is:
