The formula for circumference is

.
To express the circumference exactly, plug the diameter in for

and put the

symbol in front of it. Don't multiply. This expresses the exact circumference.
Say you have the diameter of 17.
You can express the circumference with 17

.
Answer:multiply the percent times 100
Step-by-step explanation:
<h2><em><u>Answ</u></em><em><u>er</u></em><em><u>:</u></em><em><u>-</u></em></h2>
★ Input of the given function F(x) is 5.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
<h3>• <u>Given</u><u>:</u><u>-</u></h3>
✯ F(x) = 7x - 9
✯ Output = 26
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
<h3>• <u>Solution</u><u>:</u><u>-</u></h3>
According to the question the output is 26.
Hence, the above data can be written in an equation form.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
➪ F(x) = 7x - 9 = 26
➪ 7x = 26 + 9
➪ 7x = 35

Therefore, F(x) = 5
X = -230/3 hope that helps
Ia=5/2*9.3^2(5+2--5)
a=665.47unit ^2
which then means 663.1
