Circumference of the circular flower bed=88 m
2πr=88
2×(22/7)×r=88
(44/7)r=88
r=88/(44/7)=14 m
Area =πr² sq.units
(22/7)×14×14=616 m²(Ans.)

Answer:

The area of a circular flower bed is 615.44 m² .

Step-by-step explanation:

Formula

Circumference\ of\ a\ circle = 2\pi r

Area\ of\ a\ circle = \pi r^{2}

Where r is the radius of a circle .

As given

The circumference of a circular flower-bed is 88 m.

\pi = 3.14

Putting the values in the circumference of a circle .

88= 2\times 3.14\times r

88=6.28r

r = \frac{88}{6.28}

r = 14 (Approx)

Put the values in the area formula

Area\ of\ a\ circular\ flower\ bed=3.14\times 14\times 14

Area\ of\ a\ circular\ flower\ bed=615.44\ m^{2}

Therefore the area of a circular flower bed is 615.44 m² .
