Question

ABCD is a rhombus with side length 10cm. Angle ADC=40 degree.Angle DAC is a sector of a circle with centre D. Angle BAC is a sector of a circle with centre B. Calculate the shaded area?

Answer 1

Step-by-step explanation:

find the sector area by using the formula = (¤/360)*πr^2

and find the area of the triangle DAC by the formula (1/2)absinC

then subtract triangle area from sector area

then multiply resultant area with 2
