Question

Find the area of the white region

Answer 1

Area = 51.89cm^2

Explanation:

`The- region- is- a -segment\\r = 7cm\\\alpha = 150\\A = (\alpha )/(360) * \pi r^2 -(1)/(2) * r^2Sin\alpha \\\\A = (150)/(360) * 3.142 *7^2 -(1)/(2) * 7^2 * Sin 150\\A =5/12 * 3.142 *49- (1/2* 49 *1/2)\\A = 64.149-49/4\\A = 51.89`
