Square's area= length/width^2
so then to find out the length or width (since they are the same in a square) you do the square root of 25 which is 5 since 5 times 5 is 25
so the square's length is 5cm
Step-by-step explanation:
The number divisible by 10 need to be even and divisible by 5, because the prime factors of 10 are 5 and 2. So, it means that for the number to be divisible by 10, the last digit needs to be a zero.
Answer:
($14.37 was the original price)
Step-by-step explanation:
The answer is 30 because 5×6=30 and 6×5=30.So the smallest number of books each could have shelved is 30 books...
Circumference = 2 * pi * r, where r is the radius
For this circle, the circumference is 11pi, so 11pi=2*pi*radius. Divide both sides by 2pi and you get r is = to 5.5 inches.
Area of a circle is pi*r^2. Since we just saw that r = 5.5 inches, the circle has an area of 5.5 inches * 5.5 inches * pi or 30.25 pi inches squared.
