Answer:

Step-by-step explanation:

arc between cars = 360°/25 = 14.4°

θ = 14.4° × π/180 ≅ 0.2512 radian

r = 150/2 = 75 ft

s = rθ = 75×0.2512 = 18.84 ft

area of circle = πr² = 75²π ≅ 17,662.5 ft²

area of sector = 17,662.5/25 = 706.5 ft²

I am a number less than 100. I am a product of two prime numbers. If you reversemy digits, I am a prime. The sum of my digits is
almond37 [142]

Answer:

You are number 34

Step-by-step explanation:

* Lets explain how to solve the problem

- The number is less than 100

∴ The number is 2-digit  number

- The number is the product of 2 prime numbers

∴ The two prime numbers could be two of these numbers:

   2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 , 29 , 31 , 37 , 41 , 43

∵ The number is less than 100

∴ The two prime numbers are 1-digit numbers OR one of them

   is 1-digit and the other is 2-digit

- The sum of its digits is a 1-digit

∴ The sum of its digits is less than 10

- One of its digit is a square number

∴ One of its digit is 1 or 4 or 9 because they are square numbers

* Look to the prime number above the number and chose two of

  them try to find the answer

- Start with the product of 1-digit prime numbers

∵ 2 and 7 are prime numbers

∵ 2 × 7 = 14 and the sum of its digits is less than 10 (1 + 4 = 5)

∵ 14 < 100

∵ The reversed of its digits obtained 41 which is a prime number

∵ 4  and 1 are a square number (1² = 1 or 2² = 4)

∴ The number is not 14

- Chose one of them 1-digit and the other 2-digit

∵ 2 and 17 are prime numbers

∵ 2 × 17 = 34 and the sum of its digits is less than 10 (3 + 4 = 7)

∵ 34 < 100

∵ The reversed of its digits obtained 43 which is a prime number

∵ 4 is a square number (2² = 4)

∴ The number is 34

* You are number 34
