  • \( 154 \, \text{cm}^2 \)
  • \( 49 \, \text{cm}^2 \)
  • \( 22 \, \text{cm}^2 \)
  • \( 44 \, \text{cm}^2 \)
Show Solution

The Correct Option is A

Solution and Explanation

Procedure 1: Apply the circle area formula
The area \( A \) of a circle is calculated using the formula:\[A = \pi r^2\]Variable definitions:- \( r \) denotes the circle's radius.- \( \pi \) is approximately \( 3.14 \).
Procedure 2: Input the specified radius
Provided information:- Radius \( r = 7 \, \text{cm} \).Insert \( r = 7 \) into the formula:\[A = 3.14 \times (7)^2 = 3.14 \times 49 = 154 \, \text{cm}^2\]
Conclusion:
Consequently, the circle's area measures \( 154 \, \text{cm}^2 \). The correct option is (1).
