Answer:
Answer is 330
Step-by-step explanation:
[tex]area \: of \: shaded \: region \: = \pi {r}^{2} - \pi( {x}^{2} \\ here \: r = 11 \: cm \: and \: x = 4 \: cm \\ area \: of \: a \\ shaded \: regoin \: = \pi( {r}^{2} - {x}^{2} ) \\ = \pi( {11}^{2} - {4}^{2} ) \\ = \pi(121 - 16) \\ = \pi(105) \\ = \frac{22}{7} \times 105 \\ = 22 \times 15 \\ = 330 \: {cm}^{2} [/tex]
AREA OF SHADED REGION =330
