To find the radius of a circle when given the diameter, we use the fact that the radius is half the length of the diameter. The diameter of a circle is the straight-line distance from one side of the circle to the other passing through the center. The radius is the distance from the center of the circle to any point on the perimeter.
So, given that the diameter (d) of the circle is 98 meters, we calculate the radius (r) as follows:
[tex]\[ r = \frac{d}{2} \][/tex]
Substituting the given diameter:
[tex]\[ r = \frac{98\ \text{m}}{2} \][/tex]
Now, dividing 98 by 2:
[tex]\[ r = 49\ \text{m} \][/tex]
So the radius of the circle is 49 meters.
