The document provides calculations to find the arc length and sector area of a circle with a central angle of 117 degrees and a radius of 813.42 meters. It first calculates the central angle as 117 degrees, then uses this to find the arc length as 528.7π meters and the sector area as 215036.9π square meters.

Central angle = 328.24 – 211.31=116.93 = 117°
Radius = 813.42m
Arc length = 117/360 x 2 rπ
117/360 x 2 x 813.42
528.7π m

Central angle = 328.24 – 211.31=116.93 = 117°
Radius = 813.42m
Sector area = 117/360 xπ r²
117/360 x (813.42)²
215036.9π sq meters
