Answer 1

Answer:

52.665 cm²

Step-by-step explanation:

Using, pythagoras theorem in triangle ADC,

Diagonal of the rectangle = Root((5²+12²)cm²)

= Root(25+144cm²) = Root(169cm²) = 13 cm

Because diagonal of the rectangle is also the diameter of the circle,

Therefore, radius of circle = 13/2 cm

Area of circle = Pi×r² = 3.14×13/2×13/2 = 132.665 cm²

Area of rectangle = 12×5 = 80 cm²

Therefore, Area of shaded region = Area of circle - Area of rectangle = 132.665 - 80 = 52.665 cm²

Answer 2

lrespiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction.
