Question

Perimeter of a semicircular field is 108 meters. Let us calculate the diameter of the field.

Answer 1

Answer:

42m

Step-by-step explanation:

Circumference (perimeter) of semicircular field= 108 m

πr+2r=108m

r(π+2)=108

r=108/(π+2)

r=108/(3.14+2)

r=108/5.14

r=21.0116≈21

Diameter=2r=2×21=42m
