| The side of the square is 2.6 cm long. What is the radius of the circle? How many times is the area of a square larger than the area of a circle?
The radius of the circle is: a: 2 = 2.6: 2 = 1.3
The area of a square can be found by the formula:
S1 = a ^ 2 = 2.6 ^ 2 = 6.76 (cm squared)
We find the area of a circle by the formula and based on the condition:
S2 = P * r ^ 2 = 3.14 * 1.3 = approximately 5.3 (centimeters squared)
Next, we find the ratio of these areas:
K = 6.76: 5.3 = approximately 1.27 times
Answer: the area of the square is about 1.27 times larger
