In the circumference formula given d is the diameter which is 2 times r ( r is the radius)
R is given as 6 feet, diameter = 2 x 6 = 12 feet.
Circumference = 12 feet x 3.14 = 37.68 feet
/ symbol is used for division.
/ is same as ÷
Sometimes, fractions are shown as ratio, in which case, : symbol is used.
We can write the fraction

as 1/2 or 1÷2 or 1:2
Answer:
-6.8
Step-by-step explanation:
its kinda hard to explain this problem
Solution:
X^2+11x+30
=X^2+(6+5)x+30
=X^2+6x+5x+30
=X(x+6)+5(x+6)
=(X+6)(x+5).
So,the answer is (x+6)(x+5).
