Ответ:
You didn't list the answers but it's 43.98 so close to 44 I'm guessing
Step-by-step explanation:
circumference=2*pi*r
2*3.14*7=about 44
Ответ:
Approximately 22 or 7πcm
Step-by-step explanation:
The ratio between the circumference of a circle and its diameter is π. We commonly write c=2πr, using the radius instead and doubling.
In the given example, we are told that the diameter is
7 cm. So using the common approximation π≈
we find that the circumference is approximate:
