Question

find the perimeter of a semicircular plot whose diameter is 28 metres​

Answer 1

Answer:

72

Step-by-step explanation:

Diameter = 28 m

Radius = d/2

Radius = 14 m.

Perimeter of semicircular plot = πr+ 2r

= 22/7×14+2×14

= 22× 2+ 28

= 44+28

= 72 metres

Perimeter of semicircular plot is 72 metres.
