We must use a certain formula to find the circumference. The formula for circumference of a circle is:
C = 2 * pi × r
Substitute:
C = 3.14 × 6.1 × 2
C = 38.303
Round to the nearest tenth:
38.3.
ANSWER:
The circumference of the circle is about 38.3 centimetres.
N^4 - 11 n² + 30 = ( n² - 6 ) ( n² - 5 )
n^4 - 7 n² + 10 = ( n² - 2 ) ( n² - 5 )
( n² - 6 ) ( n² - 5 ) / ( n² - 2 ) ( n² - 5 )=
Answer:
x+6
