Question

A chord of circle of radius 14cm subtends an angel of 120° at the center find the area of the corresponding minor segment of the circle

Answer 1

Area of segment is = area of sector - area of triangle
=
$\alpha \div 360 \times \pi \times r {}^{2} - (1 \div 2 \times b \times h)$
$= 120 \div 360 \times \pi \times 14 {}^{2} - 1 \div 2 \times \\ b \times h$
