Question :
Find the area of the shaded figure.
Answer :
40192 mm²
Explanation :
the area of the circle inside
= phi × r × r
= 3,14 × 40 mm × 40 mm
= 314/100 × 40 mm × 40 mm
= 5024 mm²
large circle area
= phi × r × r
= 3,14 × 120 mm × 120 mm
= 314/100 × 120 mm × 120 mm
= 45216 mm²
broad shaded
= 45216 mm² - 5024 mm²
= 40192 mm²
