Question

perimeter of a semicircular field is 108m,then find the diameter of the field​

Answer 1

Answer:

approximately 69m

Step-by-step explanation:

radius

Perimeter of the semicircular field = half circumference + diameter of the circle.

= πr + d

Therefore ,108 = πr + 2r

108 = r(π + 2)

r = 108 ÷ (π + 2)

r = 108 ÷ (22/7 + 2)

r = 108 ÷ 36/7

r = 108 x 7/36

r = 34.3m

d = 2r = 68.7
