Question

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

Answer 1

Answer:

area of semi circle is 9.81 cm²

Step-by-step explanation:

Given, radius r = 2.5 cm

As we know,

Area of semicircle = πr² / 2

Taking π as 3.14,

area of semicircle = 3.14 x 2.5 x 2.5 / 2 = 9.81 cm² (approx)

So, the area of semicircle is 9.81 cm².
