Question

What is the approximate area of the shaded region? 6 5 3 a 2 1 X 0 1 2 3 4 5 6 O A. 3 units? B. 6 units c. 10 units D. 13 units

Answer 1

Area aof shaded region is

Difference of areas between square, and circle

Area of square is = (5-1)^2 = 16

Area of circle is = π•[(5-1)/2]^2 = π•2^2 = π•4

Shaded Area = 16 - (π•4) = 16 - 12.564 = 3.436

THEN option A , is the value most aproximate to 3.436
