Question

Find the area of the sector of a circle with radius 4 cm and the angle

at the centre is 45°. (π = 3.14)

Answer 1

Answer:

Step-by-step explanation:

area of the sector =∅/360×πr²

45/360 ×3.14 ×4×4

0.125×50.24 = 6.28cm²

Answer 2

Answer:

6.28cmsquare

Step-by-step explanation:

r=4

angle at centre=45*

ar off sector=angle[teta]by360 into pi into r square

 =45by360into22by7into[4]^2

 =1by8into22by7into16
