Answer: A. The number 23 is prime, but 36 is composite.
=====================================================
Explanation:
Let's go through the possible answer choices
- A) This is true because 23 only has the factors 1 and 23. So that's why 23 is prime. We can say 36 is composite since 2 is a factor, ie 36 = 2*18.
- B) This is false because 33 is not prime. Note how 33 = 3*11, showing that 3 is a factor of 33.
- C) Similar to B, the statement "21 is prime" is false. Note how 21 = 3*7.
- D) Like the other false statements, 27 is not prime because 27 = 3*9.

Answer:
Area of circle= 81π
Area of triangle= 371.8 yards
Step-by-step explanation:
<em>2) Area of circle = πr²</em>
<em>Area of circle = π*(18/2)²</em>
Area of circle = 81π
Therefore, the area of circle is 81π.
<em>4) Area of triangle = 1/2*base*height</em>
<em>Area of triangle = 1/2*22*33.8</em>
Area of triangle = 371.8 yards
Therefore, the area of the triangle is 371.8 yards.
