Answer:
Step-by-step explanation:
If the circumference of the circle is x cm the perimeter of the square will be 38-x cm.
The area of the square = (38-x)^2.
The radius r of the circle = circumference /2π = x / 2π.
The area of the circle = πr^2 = π * (x / 2π)^2
= x^2/ 4π.
So total area A = (38 - x)^2 + x^2/4π
A = 1444 - 76x + x^2 + x^2/ 4π
A = x^2 - 76x + 0.07958x^2 + 1444
A = 1.07958x^2 - 76x + 1444

Answer the correct option is D
Step-by-step explanation:
The die has six sides. The numbers on each side are 1, 2, 3. 4, 5 and 6. This means that the total number of possible outcomes is 6
The numbers greater than 2 are 3, 4, 5 and 6. It means that there are four numbers out of 6 that are greater than 2. So the probability of rolling a number greater than 2 is 4/6 = 2/3.
Again, the numbers lesser than 5 are 1,2,3 and 4 . there are 4 numbers. So the probability of rolling a number lesser than 5 is 4/6 = 2/3
But both probabilities are mutually non exclusive. It means that 3 and 4 is common. The probability of rolling a 3 and a 4 = 1/6 + 1/6 = 2/6 = 1/3.
Therefore, the probability of rolling a number greater than 2 or less than 5 would be 2/3 + 2/3 - 1/3 = 3/3 = 1
