Question

Find the area of the shaded region from the given figure

Answer 1

Answer:

area of shade region is =. (side)2 - area of circle

(10)2 - 3.14× 3.5 ×3.5

100 -38

62 is the answer

Answer 2

Answer:

61.5 cm²

Step-by-step explanation:

Given -

A shaded square = 10 cm side

A unshaded circle inside the square = 3.5 cm radius

To find -

The total area of shaded region

Solution -

Shaded area = square's area - Circle's area

$= ( {side}^{2} ) - (\pi {r}^{2} ) \\ = (10 \times 10) - ( \frac{22}{7} \times 3.5 \times 3.5) \\ = 100 - ( \frac{22}{7} \times \frac{35}{10} \times \frac{35}{10} ) \\ = 100 - ( \frac{22 \times 5 \times 35}{10 \times 10} ) \\ = 100 - ( \frac{22 \times 35}{2 \times 10} ) \\ = 100 - ( \frac{11 \times 35}{10} ) \\ = 100 - ( \frac{385}{10} ) \\ = 100 - 38.5 \\ = 61.5 {cm}^{2}$

Hence shaded region = 61.5 cm²
