d1 = 2R;
d2 = 2 * d1;
d2 = 2 * 2R;
2 times.
Answer: It is necessary to increase the radius by 2 times.
Explanation: Since the diameter of the circle must be doubled, we can write d2 = 2 * d1. We express d1 in terms of the radius, substitute it into the formula. We see that it is necessary to take 2R * 2, that is, increase the radius by 2 times.
