Question

if the area of a semicircular field is 30800 square metre then the perimeter of the field is

Answer 1

Area of semicircle

πr^2/2=30800

After solving u will get ready=140

Perimeter of semicircle=πr

22/7*140

22*20=880m

Answer 2

hєчα

hєrє íѕ thє αnѕwєr

gívєn :-

αrєα σf ѕєmícírculαr fíєld = 30800 m²

αlѕσ,

αrєα σf ѕєmícírculαr fíєld = (πr²) / 2

ѕσ,

(πr²) / 2 = 30800

πr² = 61600

22/7 × r² = 61600

r² = 19600

r = √19600

r = 140 m

nσw

pєrímєtєr σf thє fíєld = 2πr

=> 2 × 22/7 × 140

=> 880 m

hσpє thíѕ hєlpѕ.
