Find the circumference of a circle whose diameter is 49cm
The circumference (C) of a circle can be found using the formula C = πd, where d is the diameter of the circle and π is a mathematical constant approximately equal to 3.14159.
Given that the diameter (d) of the circle is 49 cm, the circumference (C) can be calculated as follows:
C = π * d
= 3.14159 * 49 cm
≈ 153.938 cm
Therefore, the circumference of the circle is approximately 153.938 cm.
To find the circumference of a circle, you can use the formula:
Circumference = π * diameter
Given that the diameter is 49 cm, we can substitute this value into the formula:
Circumference = π * 49 cm
Now, let's calculate the circumference using the value of π (pi), which is approximately 3.14159:
Circumference ≈ 3.14159 * 49 cm
Circumference ≈ 153.937 cm
Therefore, the circumference of a circle with a diameter of 49 cm is approximately 153.937 cm.
