Question

For each of the following figure ,find
its perimeter,
its area
ans should be
56.5cm
191cm
give correct ans ​

Answer 1

Answer:

Perimeter if given figure=56.57 cm

area of given figure = 191 Sq cm

Step-by-step explanation:

area of semi circle= π r^2/2

r= 9/2 cm

R= = 18/2=9 cm

area of given figure = area area of two small semi Circles+are of big semi circle

2πr^2+πR^2

=2 × [π (9/2)^2/2]+ π (9)^2/2

= π 81/4+π81/ 2

= π 81×3/2

=243π/2 Sq cm

= 242×22/(7×2)

=190.928571

= 191 Sq cm

Perimeter if given figure= 2× Perimeter if small semicircle + Perimeter of big circle

= 2πr+πR

= π × (2r+R)

= π× (9+9)

= 22/7×18

=22×18/7

= 56.57

Perimeter if given figure=56.57 cm

Perimeter if given figure=56.57 cmarea of given figure = 191 Sq cm
