Question

20 meters of wire is available for fancing
off a flower-bed in the form of a circular
sector of radius 5 meters, then the
maximum area (in sq. m.) of the flower-
bed is​

Answer 1

Answer:

2

Step-by-step explanation:

diameter = 2×radius

5×2=10

20÷10=2

Answer 2

Answer:

50

Step-by-step explanation:

'S' is the length of arc

'r' is radius

'A' is area of flower bed

S=20m=r*@                                              {@ is theta}

r=5m

A= ? =(r^2*@)/2

therefore, 20=(5)(@)

therefore @=4radians

therefore A=(5^2*4)/2

A=25*2

therefore A=50
