Question

The figure show the sector
of a circle o and radius 14. What is the berimeter
perimeter, in cm
of the figure?​

Answer 1

Answer:

Substitute r=14 cm and θ=45 in the formula Ps=2πr×(θ360)+2rto determine the perimeter of the sector subtending 450 of the angle at the center.

Hence, 39 cmis the perimeter of the sector subtending 450 of the angle at the centre of the circle whose radius is14 cm.
