2 10,8,100
2 5, 4, 50
2 5, 2, 25
5 5, 1, 25
5 1, 1, 5
1, 1, 1
2*2*2*5*5=200
4/10=4*200110
=80
5/8=5*200/8
=125
38/100=38*200/100
=76
76,80,125
The answer is 38%,0.4,5/8
Formula for finding circumference of a circle is 2πr.
Step-by-step explanation:
- The given question says what is the circumference of a circle that is 9cm.
- As radius is required for finding circumference of a circle, the formula is 2πr.
- Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
- If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
- So the circumference of the given circle would be 18π or 56.52 cms.
