Question

if the area of a semicircular field is 3850 square metre then perimeter of the field is​

Answer 1

Step-by-step explanation:

let us consider 'r' as the radius of the given semicircular field.

then,

area of the given field = 3850 m²

or, πr²/2 = 3850 m²

or, 22/7 × r² × 2 = 3850 m²

or, r² = 3850 × 7 × 2 / 22

or, r = 49.99

therefore

perimeter = πr+2r
