Question

if the radius of a circle is 2.5 cm , what is the area of its semi-circle​

Answer 1

Answer:

Step-by-step explanation:

Area of Semi-Circle = $\frac{1}{2}$ × π × r²

⇒ $\frac{1}{2}$ × $\frac{22}{7}$ × 6.25                                           (r × r = 2.5 × 2.5 = 6.25)

⇒ $\frac{11}{7}$ × 6.25

⇒ 9.82 cm²

Therefore, Area of the circle is 9.82 cm² approximately.
