Answer:
A ≈ 904.8 cm²
Explanation:
the area of a circle is calculated as πr² ( r is the radius )
the area (A) of the semicircle , that is half of the circle is
A =
πr²
the diameter of the semicircle is 48 cm then r = 48÷ 2 = 24 cm , so
A = 0.5 × π × 24²
= 0.5 ×π × 576
= 288 × π
≈ 904.8 cm² ( to 1 decimal place )
