Question

The Figure shows a circle with centre O and angle AOB=90°. If the radius of the circle is
40cm,calculate the area of the shaded potion of the circle​

Answer 1

Step-by-step explanation:

GIVEN,

• ANGLE AOB=90°
• RADIUS OF CIRCLE=40cm

area of the segment=1/4πr²

=1/4*22/7*40*40

=256.6cm²

AREA OF TRIANGLE AOB=1/2*40*40

=800cm²

so area of shaded region=256.6-800

=456.63cm²

Answer 2
