Final answer:
The circumference of a circle with a radius of 2.6 meters is calculated using the formula C = 2πr, resulting in approximately 16.34 meters rounded to two significant figures.
Step-by-step explanation:
To find the circumference of a circle with a radius of 2.6 meters, we use the formula for the circumference of a circle, C = 2πr, where 'r' is the radius of the circle and π (pi) approximates to 3.14159. Thus, for a circle with a radius of 2.6 meters, the circumference is calculated as follows:
C = 2π(2.6 m)
C = 2 × 3.14159 × 2.6 m
C ≈ 16.336314 m
Therefore, the circumference of the circle is approximately 16.34 meters, rounding to two significant figures.
