the circumference of a circle is equal to the perimeter of a square. The area of a square is 484 square meter. Find the area of the circle

Answer»

Answer:

616m²

Step-by-step explanation:

AREA of SQUARE = s²

484 = s²

s = √484 = 22m

PERIMETER of square = 4×s = 4×22 = 88m

Hence, Circumference of circle = 88m

(circumference of circle = perimeter of square )

2πr = 88

2×22/7×r = 88

r = 88×7/22×2 = 14m

Area of circle = πr² = 22/7×14² = 616m²
