Answer:
The diameter is 10
Step-by-step explanation:
When it comes to a circle, the radius is half of the length of the circle or the length of the center of a circle to the circumference of the circle. the diameter is the full length of one side of the circle to the other side while going through the center. This means the diameter is double the radius since it goes through the circle all the way while the radius is only halfway. This then makes us get the answer by multiplying the radius by 2 to get the diameter. 5x2=10
