Answer:
The area of shaded region is 177.06cm²
Step-by-step explanation:
Firstly, you have to find the area of circle with the formula, area=π×radius² using the following values:
radius = 8cm
A = π × 8²
= 64π cm²
Secondly, you have to find the area of rectangle:
A = length × breath
= 12 × 2
= 24cm²
Lastly, you have to substract rectangle from circle in order to find the area of shaded region:
A = 64π - 24
= 177.06 cm² (near. hundreath)
(Hope the answer is correct)
