Final answer:
The distance around the steering wheel is the circumference, calculated as C = 2πr. With a radius of 7 cm, the distance around the steering wheel is C = 14π cm.
Step-by-step explanation:
The distance around a steering wheel, which is essentially the circumference of a circle, is calculated using the formula C = 2πr where r is the radius of the circle and π (pi) is approximately 3.14. Given that the radius of the steering wheel is 7 cm, the distance around the steering wheel can be found by plugging the values into the formula:
C = 2 × 3.14 × 7 cm
C = 2 × 3.14 × 7 cm = 43.96 cm
However, the options given are in terms of π, so we leave the term π in the equation:
C = 2 × 7π cm
C = 14π cm
Therefore, the correct answer from the given options is a. 14π cm.
