Question

A pond is in the shape f a semi-circle. The diameter of the pond is 11 feet. What is the perimeter of the pond?

Answer 1

We know that,

`\boxed{ \red{ \mathfrak{Perimeter \: of \: semi - circle =\pi r + 2r }}}`

We are given;

• π = 22/7
• r = 11 feet

`\pink \longmapsto \purple { \mathfrak { Perimeter= (22)/(7)*11 +22 }}`

`\pink \longmapsto \purple { \mathfrak { Perimeter= (242)/(7)+22 }}`

`\pink \longmapsto \purple { \mathfrak { Perimeter= (396)/(7)}}`

`\pink \longmapsto \purple { \mathfrak { Perimeter= 56.5 \: cm}}`
