Question

A wire in the shape of a square of side 10 cm is reshaped into a sector of the circle with radius 10 cm..The angle of the sector in radians

Answer 1

side of a square=10 cm

radius of the sector =10 cm

circumference of a circle =2×3.14×10

=62.8cm

the length of the wire into a sector =62.8×10 =628.0cm
