fill blanks give values of cin terms of pi if r=7m then d=?and c=?

If you are talking about a circle,

c = πd, so if πd = 7π, then d = 7m
d = 2r, so r = 3.5m

To find the values of diameter (d) and circumference (c) given that the radius (r) is 7m, we can use the formulas:

1. Diameter (d) = 2 * radius (r)
2. Circumference (c) = 2 * π * radius (r)

Let's fill in the blanks using the given value of the radius (r = 7m):

1. Diameter (d) = 2 * radius (r) = 2 * 7m = 14m
- The diameter of the circle is 14 meters.

2. Circumference (c) = 2 * π * radius (r) = 2 * π * 7m ≈ 44m
- The circumference of the circle is approximately 44 meters.

Therefore, if the radius (r) is given as 7m, then the diameter (d) would be 14m, and the circumference (c) would be approximately 44m.
