Part A-Circumference of a circle
1 answer:
The circumference of a circle with a diameter of 10 cm is 31.4cm.
The circumference of a circle is its edge or the measurement of its entire arc.
The circumference of a circle with radius is
.
The circle in question has a diameter of 10 cm.
The radius of a circle's diameter is equal to its length divided by two. Consequently, the given circle's radius is 5 cm.
If we assume that π=3.14, then the given circle's circumference will be equal to 2×π×5. Consequently, 31.4 cm is the required circumference.
As a result, a circle with a diameter of 10 cm has a 31.4 cm circumference and it has been expressed in three significant figures.
