Answer:
1/5
Step-by-step explanation:
Diameter is 2.36 cm.
Given:
Circumference = 7.38 cm
Circumference of a circle is computed by multiplying 2, pi, and its radius.
C = 2πr
7.38 = 2 (3.14) r
7.38 = 6.28r
7.38/6.28 = 6.28r/6.28
1.18 = radius
Diameter = 2r
Diameter = 2(1.18)
Diameter = 2.36 cm
If x is the average of "the other 20 numbers", then their sum is 20x. Adding the 21st number makes the sum of all 21 numbers be 20x +4x = 24x.
The 21st number, 4x, is 4x/(24x) = 1/6 of the total of all numbers,
Answer:
6/2=3
3*10=30
10*3.14=31.4
30+31.4=61.4 or rounded to 61
