Question

find the perimeter of adjoining figure ,which is a semicircle including it's diameter ​

Answer 1

Answer:

πr+10

Step-by-step explanation:

22/7 x 5+10

= 25.71 cm

Answer 2

Answer:

Given that ;

Diameter of the Semi Circle ( d ) = 10cm

Radius of the Semi Circle ( r ) = d / 2

= 10 / 2

= 5cm

Radius of the Semi Circle ( r ) = 5cm

Perimeter of the Semi Circle ( P )

π r + 2 r

Perimeter = Circumference of Semi Circle

= π r + 2 r

= 22 / 7 × 5 + 2 ( 5 )

= 112 / 7 + 10

= 16 + 10

= 26cm

Hence ;

Perimeter ( Circumference ) of the Semi Circle

= 26cm
