the formula for the circumference of a circle is
<span>C = 2 × π × r or C = π × D </span>
<span>If either r or D is known, you can calculate the circumference by simply substituting the known value for r or D in the formula. Use 3.14 for π.
</span>RADIUS = 10DIAMETER = 20
C IS THE ANSWER
Answer:
Substitution
Step-by-step explanation:
Subtitue x=3 into the second equation
y=2(3)+1
y=6+1
y=7
The answer is $108.60 because $25.67 x 3= 77.01+ $23.55= 100.56 x 8% = $8.0448 + $100.56= $108.60
