The area of the sector to 3 significant figure is 1480cm²

Area of a sector.

The formula for calculating the area of a sector is expressed as

A= r²β/2

where;

r is the radius. = 45cm

β is the central angle =84 degrees

Substitute

A = (45)²(84π)/360
A = 1483.65cm²

Hence the area of the sector to 3 significant figure is 1480cm²
