Question

find the length of the arc of the circle of diameter 8.4cm with area of the sector 18.48cm2. also find measure of the arc

Answer 1

circle diameter=8.4cm
radius=4.2cm
area of sector=18.48cm2
measure of arc=2*area of sector/radius
=2*18.48/4.2
=8.8cm

Answer 2

circle diameter=8.4cm

radius=4.2cm

area of sector=18.48cm2

measure of arc=2*area of sector/radius

=2*18.48/4.2

=8.8cm

The measure of arc as well as length of the arc are almost same, so, length of arc = measure of arc = 8.8
