The area of a semi circle is19.25 cm? Find its diameter.

The area of a semi circle is 19.25

We know that,

Area of semicircle = 1/2(πr²)

Therefore,

19.25 = 1/2 * 22/7 * r²

19.25 = 22/14 * r²

19.25 * 14/22 = r²

269.5/22 = r²

12.25 = r²

r = √12.25

r = 3.5 cm

Thus, The radius of the given semicircle is 3.5 cm

Therefore,

Diameter of the given circle = 2 * Radius

Diameter = 2 * 3.5 = 7 cm

Hence, The diameter of the given circle is 7 cm
