Area of a Sector radius 9 m with 178 m is 125.757 m²


    Area of a Sector radius 9 m with 178 m in other units

Value unit
0.125757 km²
0.078142 mi²
125.757
412.5885827 ft²
4951.0629921 in²
137.5295276 yd²
12575.7 cm²
125757.0 mm²

Steps:

Given that Radius, r = 9 m and α = 178 degrees

We know that, Area = r² * α/2

Put the radius and angle (α) values in Area Formula

A = 9² * 1780/2

Given angle (α) in degrees so convert into radians

radians = 3.1051111

Simplify the above equation

A = 125.757 m²

∴ Area of a Sector radius 9 m with 178 degrees is 125.757 m²
