Answer

The area of the circle is 153.86 cm².

Steps:
The formula for the area of a circle is A=πr2A = \pi r^2.
Given:
Radius (r) = 7 cm
π\pi = 3.14

  1. Substitute the values into the formula: A=3.14×(7 cm)2A = 3.14 \times (7 \text{ cm})^2

  2. Calculate the square of the radius: A=3.14×(49 cm2)A = 3.14 \times (49 \text{ cm}^2)

  3. Multiply by π\pi: A=153.86 cm2A = 153.86 \text{ cm}^2
