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.

Step-by-step explanation:
Divide 4 on both sides and u= 6.4/4 which the answer is equal to 1.6
they increased by 70 percent. divide 667 by 912 and you get 0.67237903 but you round to the tenths and get 70% because you move the decimal to the right twice
