Question

If the perimeter of a semicircular park is 72 metre

Answer 1

Friend please complete your question.....

perimeter of semicircle =2×Pie×R

R is radius

Pie=22/7

with this formula you can solve your question

Answer 2

formula perimeter of semicircle=2r(π+1)

so 2r(π+1)=72

2r[(22/7)+1]=72

r(30/7)=36

r=(36×7)/30

r=42/5

r=8.4meters
