Answer:
50.3 square units
Step-by-step explanation:
area of rectangle: 11 x twice the radius
radius = 2
A(rect): = 11(4) = 44 sq units
A (semi-circle) = (π·r²) / 2
A = 4π / 2 = 2π = 6.28 sq units
44.0 + 6.28 = 50.28
Keith is correct and he solved by factoring and the answers to the equation are -5 and -12
Area of shaded region = area of outer circle - area of inner circle.
288pi = pi * (2x)^2 - pi * 6^2
288 = 4x^2 - 36
4x^2 = 324
x^2 = 81
x = 9 cms Answer
