Morgan has completed the mathematical statements shown below. Which statements are true regarding these formulas? Select three options.
A = pi times r squared and C = 2 times pi times r. A = pi times r times r and C = pi times r times 2. A = (pi times r) times r and C = (pi times ) times 2.
The numerical values of the area and circumference are equal when r = 2.
The numerical value of the area is less than the numerical value of the circumference when r less-than 2.
The numerical value of the area is greater than the numerical value of the circumference when r less-than 2.
The numerical value of the area is less than the numerical value of the circumference when r greater-than 2.
The numerical value of the area is greater than the numerical value of the circumference when r greater-than 2.

Answer:
Correct options are 1, 2 and 5. Formula to calculate area and circumference :
Area = pi*r*r and Circumference = 2 * pi * r
Explanation:
- In option 1, r = 2. A = 2 ×π × r = 2 × π × 2 = 4π. C = 2 × π × r = 2 × π ×2 = 4π . So, numerical value of area and circumference are equal
- In option 2, r < 2. Let r = 1. A = π × 1 × 1 = π, C = 2 × π × 1 = 2π. So, the numerical value of area is less than numerical value of circumference.
- Option 3 is not correct as verified in option 2.
- In option 4, r > 2. Let r = 3. A = π × 3 × 3 = 9π, C = 2 × π × 3 = 6π. So, the numerical value of area is not less than the circumference.
- Option 5 is correct as showed in option 4.
