Question

1.0 Four equal elreles, each of radius 'a'touch one another. Find the area between them,
(6) Four equal circles are described about the four corners of a square so that each cuce
touches two of the others. Find the area of the space enclosed between the circumferences
of the circles, each side of the square measuring 14 cm,​

Answer 1

Answer:

Answer

AnswerConsider the figure shown.

AnswerConsider the figure shown.Now, four sector of the circles inside the square forms a circle of radius = 7cm.

AnswerConsider the figure shown.Now, four sector of the circles inside the square forms a circle of radius = 7cm.So, Area of shaded region or the area enclosed between the circumference = Area of square- Area of circle formed

AnswerConsider the figure shown.Now, four sector of the circles inside the square forms a circle of radius = 7cm.So, Area of shaded region or the area enclosed between the circumference = Area of square- Area of circle formedHence area enclosed between circumference =(142)−(πr2)

AnswerConsider the figure shown.Now, four sector of the circles inside the square forms a circle of radius = 7cm.So, Area of shaded region or the area enclosed between the circumference = Area of square- Area of circle formedHence area enclosed between circumference =(142)−(πr2)Area of the shaded region =(196)−(722×7×7)

AnswerConsider the figure shown.Now, four sector of the circles inside the square forms a circle of radius = 7cm.So, Area of shaded region or the area enclosed between the circumference = Area of square- Area of circle formedHence area enclosed between circumference =(142)−(πr2)Area of the shaded region =(196)−(722×7×7)=42cm
