Find circumference of circle with radius of 2.7 cm (round to tenth and put units)
The circumference of a circle can be found using the formula C=2πr, where r is the radius of the circle.
Given that the radius (r) of the circle is 2.7 cm, we can substitute this value into the formula to find the circumference:
C = 2π(2.7 cm)
Using the value of π rounded to the tenth (3.1), we can calculate the circumference:
C = 2(3.1)(2.7 cm)
C ≈ 17.0 cm
Therefore, the circumference of the circle with a radius of 2.7 cm is approximately 17.0 cm.
