2 answers:
The formula for circumference is C = 2<span>πr. We already know that the radius of the circle is 21 feet, so let's plug that into the equation. C = 2</span><span>π(21) Now let's simplify C = 6.28(21) C = 131.9 131.9 is your circumference.</span>
Answer:
The answer like he said is 131.9 but round it to the nearest tenth will be 132 ^^

Use angle sum property (the 3 angles in a triangle sum up to 180°).
2x + x + 54 = 180
3x + 54 = 180
3x = 180 - 54
3x = 126
x = 126/3
x = 42
