Question

The diameter of a circle is 8 m.find the circumference to the nearest tenth

Answer 1

Answer:

50.3

Step-by-step explanation:

The formula for the circumference of a circle is Area = pi * radius squared. So if the diameter is 8, then the radius is half of that, so it's 4. Now we square 4 and we get 16. Then multiply that by pi so we get 16 * pi = 50.26548. The tenth is the first # behind the decimal point, so your answer is 50.3. I hope this helped! :)
