I'm telling you, it's not from the Internet

When the ratio of circumference is constant, the diameter is in positive proportion to the circumference______ (judge right or wrong)

Because: the circumference of the circle △ diameter = π (certain),
That is to say, the quotient of circumference and diameter is certain, which conforms to the meaning of positive proportion
So the answer is: √

If the ratio of circumference is taken as 3, then the circumference of the circle △ radius=

If the ratio of circumference is taken as 3, then the circumference △ radius = 6
Circumference C = 2 π R
C/r=2π=2x3=6

The radius of a circle multiplied by pi is equal to（

It's half the circumference of a circle
Because the circumference of a circle is equal to 2 π R, then π R is half the circumference of the circle

The greater the circumference, the smaller the smaller______ (judge right or wrong)

From the analysis, we know that the diameter of the big circle is large, and the circumference of the small circle is small. The ratio of the circumference of the circle to its diameter is the ratio of the circumference of the circle to its diameter, which does not change with the change of the size of the circle;
So the answer is: wrong

Is the ratio of circumference of small circle equal to that of large circle

Yes, of course!

The Pi of a large circle is greater than that of a small circle______ (judge right or wrong)

According to the definition of PI, PI is the ratio of circumference to diameter of a circle. It is a constant and constant. Therefore, the Pi of large circle and small circle is not distinguished
So the answer is: ×

1. The circumference ratio of the big circle is larger than that of the small circle 2. If the circumference of two circles is equal, the area of the two circles must be equal. () 3. If the diameter of a circle is 4cm, its circumference and area are equal. () 4. The longer the radius is, the greater the circumference is and the larger the area is. () 5. A rope of the same length is enclosed into a circle or a square, The area of a circle is larger than that of a square

1. Wrong (PI is a fixed value, regardless of the size of the circle.) 2. Right 3. Wrong (perimeter and area units are different, so they can't be equal.) 4. Wrong (the value of PI is fixed, so it doesn't change with the radius) 5. Right 6. Right

The ratio of circumference to diameter of a circle is the ratio of circumference to diameter, which is a definite number

It must be right!
come on.
