Question

twenty meters of wire is available for fencing off a flower bed in the form of a circular sector. Then the maximum area ( in sq. m ) of the. flower- bed is please do answer if you don't know

Answer 1

➡HERE IS YOUR ANSWER⬇

Let, the radius of the circular flowerbed be r m.

The circumference of the circular flowerbed
= The length of the wire

or, 2×π×r = 20

or, r = 10/π

So, radius of the circular flowerbed
= 10/π m.

Therefore, the area of the circular flowerbed

= π × r^2

= π × (10/π)^2 sq-m

= 31.83 sq-m (approximately)

Answer 2

hiii!!!

here's ur answer...

ATQ,

20m is available for fencing a circular flower bed.

therefore circumference of the circular flower bed = 20m

==> 2πr = 20m

==> 2 × 22/7 × r = 20m

==> 44/7 × r = 20m

==> r = 20/1 × 7/44

==> r = 140/44 = 70/22 = (35/11)m

area of the circular flower bed = πr²

= 22/7 × 35/11 × 35/11

= 2 × 5 × 35/11

= 350/11

= 31.81m² (approximately)

= 32m²

hope this helps u...!!
