Answer:
step 2
Step-by-step explanation:
Given
p = 2l + 2w ( subtract 2w from both sides )
p - 2w = 2l ← correct step 1
Now, divide both sides by the multiplier 2
= l
13 + 21 = 13- -21
The minus sign and negative cancel each other out.

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
