Find the area of a sector of a circle

Question

Find the area of a sector of a circle with a central angle of 310 degrees and a radius of 30 cm

Answer 1

The area, A, of the sector is proportional to the area of the entire circle.

A / 310 = π(30)² / 360

360A = 900π(310)

A = 900(310) / 360 = 775π cm²
