Answer:
Step-by-step explanation:
Arc length has a formula of
and we have all the info we need to solve for the radius, which we will then use in the circumference formula:
and simplifying a bit,
and a bit more,
. Multiply both sides by 9:
72π = πr . Divide both sides by π to get that
r = 72.
Now we will sub that into the circumference formula to find the circumference. Recall that C = 2πr.
C = 2π(72) so
C = 144π
The answer to the question is C

there is 81 student and 317 adults adults :) got u
Step-by-step explanation:
4452 = 8n + (4n-7)12
4452 = 8n + 48n - 84
4536 = 56n
81 = n
<u>Step-By-Step Solution for Part 1:</u>
- 3(4p + 2) = 12p + 6
- => (3 x 4p) + (3 x 2) = 12p + 6
- => 12p + 6 = 12p + 6

<u>Step-By-Step Solution for Part 3:</u>
- 2y + z² = y x y + z + z
- => 2y + z² = y² + 2z
<u>[Replacing y as 2 and z as 3]</u>
- => 2(2) + (3)² = (2)² + 2(3)
- => 4 + 9 = 4 + 6
- => 13 ≠ 10

<u>Step-By-Step Solution for Part 4:</u>
15n + 5 = 5(3n + 1)
=> 15n + 5 = (5 x 3n) + (5 x 1)
=> 15n + 5 = 15n + 5
