Answers
Answer:
first take a formula of a square after was convert into it circumference
Step-by-step explanation:
if you find the sum of the square you will get the circumference
Answer:
Circumference of circle = Perimeter of square
Question:-
Circumfernce of a circle and perimeter of a square are equal. The circumference of the circle is 88 cm. Find the area of the square.
Solution:-
2πr = 4s
88 = 4s
88/4 = s
22 = s
Area of square = (s)²
= (22)²
= 464 cm²
The area of the square is 464 cm².
More information:-
Suppose by chance they had asked us to calculate the area of the circle. Then what would we do?! It’s quite easy.
Circumference of circle = 88 cm
2πr = 88
2 × 22/7 × r = 88
r = 88 × 7/2 × 22
r = 4 × 7/2
r = 2 × 7
r = 14 cm
Area of circle = πr²
= 22/7 × 14 × 14
= 22 × 2 × 14
= 44 × 14
= 516 cm²
The area of circle would be 616 cm²
