<h3>given:</h3>

$d = 7 \: ft$

the circumference of the circle.

<h3>solution:</h3>

$c = \pi \: d$

$3.14 \times 7$

$= 21.98 \: ft$

hence, the circumference of the circle is 21.98 feet.

Answer:

$\sf C=21.99~ft.$

__________

$\sf Steps$

$\sf Given~the~diameter~is~7~ft...$

$\sf We~know~we~must~use~diameter-to-circumference~formula$

$\sf Formula:$ $\pi d = \pi * (diameter) = [Circumference]$

__________

$\sf Solve$

$\pi * 7 = 21.99~ft.$

Variable c is 5 more than variable

shutvik [7]

First, let us restate the given conditions

c is 5 more than variable a ( c = a + 5)
c is also three less than variable a (c = a - 3)

Now, lets look at the answer choices and or given
c = a − 5
c = a + 3
Here, c is 5 less than "a"...so automatically disqualified

a = c + 5
a = 3c − 3
Here, we have to get "C" by itself in both top and bottom equation.
So,
Simplified version :
c = a - 5
Here, c is 5 less than "a"...so automatically disqualified

a = c − 5
a = 3c + 3
Here also, we have to get "C" by itself in both top and bottom equation.
So,
simplified version:
c = a + 5
Here, c is 5 more than "a"...so we continue
c = (a - 3) / 3
Here, c is 3 less than "a" divided by 3 . So, this is not correct

c = a + 5
c = a − 3
Here, c is 5 more than "A"
Also, c is 3 less than "a"
Which satisfies the given.

So, our answer is going to be the last one:

c = a + 5
c = a - 3
