Plz explain Q22 part b

ABC kitna hai ? 73 naa ..
AEC kitna hai 146 naa ?

Angle at center = 2 angle at circumference .. ye property bun rahi hai ??
AEC jo hai woh circle 2 kay ander hai .. hence Circle I ka center Circle 2 kay ander hai ..

Plz explain Q22 part b

point E small circle ka centre haI,
q k angle at centre is twice the angle at circumfernece ....
circumfenrce per 73 hai and centre per 146 that is double ..

hmmm ..

apni post ka zara link dena dobara say...

q.22 part (b) !! plz anyone ??

Perimeter = 2 lines + arc small semi circle + arc large semi circle

2 lines = 40 cm
Small semi circle arc = 2pie x r x 1/2 x 1/4 = 5pie/2 r= 10
large semi circle arc = 2 pie x r 1/2 x 1/4 = 15 pie /2

perimeter = 40 + 10 pie = 71.4cm ..
ryt. .?

40+10 pie pe answer chorrna hoga i think .. cuz P1 hai yeh ..

 

[Mayedah]

40+10 pie pe answer chorrna hoga i think .. cuz P1 hai yeh ..

Yes u have to give answer like u did !

 

[MustafaMotani]
