Question

The area of a circular pond is 1386m². Find the length of wire required to fencr around it with 1 round.

Answer 1

132m IS THE PERIMETER

Step-by-step explanation:

πr²=13686m²

22/7r²=13686

r²=13686×7/22

r²=441

r=√441

r= 21

SO PERIMETER FORMULA IS 2πr

so accordingly__

2×22/7×r

=2×22/7×21

=132m

• SO WE REQUIRE A WIRE LENGTH OF 132 M.........
