To determine what digit the radius is closest to, you would need to know the specific value of the radius in question. If the radius is a decimal or whole number, you can round it to the nearest whole number or identify the closest digit. For example, if the radius is 4.6, it would be closest to 5; if it were 3.2, it would be closest to 3.

the circumference is 21.98 inches
The circumference is about 43.98 inches. The circumference of a circle is diameter (radius x2) x pi (3.14).
First the closest square is 52=25 so the first digit is 5 Then you write two 0 at the right of 31 -> 3100 and try to find the closest square between 50 and 59 (5 is the first digit found) The closest square to 3100 is 55, 552=3025, 562=3136, so the second digit is 5 and one gets 55 Now with 310000 and a number between 550 and 559, the closest square is 5562=309136, the third digit is 6 and so on.... So sqrt(31)=5.56....
It is 0.3 because the digit after 3 is less than 5
Mercury is the closest planet in size to the Moon. Mercury is only slightly larger than the Moon, with a diameter that is about 38% larger.

Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
It is approximately 75,000 light years in radius
the circumference is 21.98 inches
The only decimal value that is closest to 4.75 is is 4.749̅ [9̅ represents the repeated digit value for the term.]

The circumference is about 43.98 inches. The circumference of a circle is diameter (radius x2) x pi (3.14).
The volume of a sphere with a radius of 0.93 meters is: 3.369 m3

Circumference is 2 times pie (which is often rounded to 3.14) times the radius. The result is 56.52 inches.
