The formula for circumference is C = 2πr, where r is the radius of the circle. However, the radius is half the diameter, so the circumference could also be calculated using the formula C = πd, where d is the diameter of the circle. π is commonly shortened to 3.14.
If the diameter of the circle is 6 feet, an estimate of the circle's circumference is 6 times 3 feet or 18 feet.
Answer:
18 ft
Do 16-9 which equals 7, then (7)^11=77 1.=77
this one add 3+4 which equals 7 then do 7^2= 49 then 4x49=196 2.=196
The solution to 1 - cos(6x) is 2sin²(x).
Hence, option B) 2sin²(x) is the correct answer.
<h3>What is solution to 1 - cos(6x)?</h3>
Given that; 1 - cos(6x) = ?
First, we rewrite using trig identity
1 - cos(2 × 3x)
Using the double angle identity, { <em>cos2(x) = 1 - 2sin²(x)</em> }
1 - ( 1 - 2sin²(x) )
Eliminate the parentheses
1 - 1 + 2sin²(x)
2sin²(x)
The solution to 1 - cos(6x) is 2sin²(x).
Hence, option B) 2sin²(x) is the correct answer.

Answer:
to what?
Step-by-step explanation:
Answer:
x=-5
Step-by-step explanation:
Denominators are:
x+5, 5, and 5x+25
5 cannot be turned to 0 since it does not have a variable.
So we have x+5 and 5x+25.
eqyal each denominator to 0 since that is what we want.
x+5=0 5x+25=0
x=-5 5x=-25
x=-25/5
x=-5
∴x=-5 for all denominators to make 0.
