Answer: The diameter is 20 units, the circumference is 
or about 62.83, and the area is 
or about 314.16
Step-by-step explanation:
To get the diameter, you can mutiply the radius by 2. (10*2= 20)
To get the circumference, you can use the equation 
, substituting r for the radius. For an exact answer, use pi. For an approximate, do only 2 times the radius and append pi to the answer ().
To get the area, you can use the equation 
, substituting r for the radius. For an exact answer, use pi. For an approximate, do only the radius squared ().
Answer:
that's 3 unit s so because it's 3.5 but round it up and u get 3
