Question

four equal sized maximum circular plates are cut off from a square paper sheet of area 784cm2 .what is the circumference of each plate ​

Answer 1

Answer:

Area of 1 circular plate = 784cm²/4

=πr²= 196cm²

=(22/7)×r²=196cm²

=r²=(196cm²×7)/22

=r²=62.36cm²

=r=√62.36cm²

=r=7.9cm

Circumference of each plate is

=2πr

=2×(22/7) ×7.9cm

=49.65cm
