Full solution

Q. Find the area of semicircle. 1111cm
  1. Identify formula: Identify the formula for the area of a circle, A=πr2A = \pi r^2, and then divide by 22 for a semicircle.
  2. Plug in radius: Plug in the radius r=11 cmr = 11\,\text{cm} into the formula: A=(π⋅112)/2A = (\pi \cdot 11^2) / 2.
  3. Calculate area: Calculate the area: A=(π×121)/2A = (\pi \times 121) / 2.
  4. Simplify calculation: Simplify the calculation: A=(3.14×121)/2A = (3.14 \times 121) / 2.
  5. Perform multiplication: Perform the multiplication: A=379.942A = \frac{379.94}{2}.
  6. Divide for final area: Divide by 22 to find the final area: A=189.97 cm2A = 189.97 \, \text{cm}^2.
