I believe your mistake is that you are trying to use the sector area formula ti find arc length when there is already a formula for it.
The formula for it is

So first substitute the values in and then simplify!

Now simplify!
21 × 118 is 2478 so it's

When divided ou and multiplied, this is 21.62cm!

B<span>oth triangles are 30 60 90 triangles.
Perhaps the way to prove this is by showing that (AD/BD) and (AD/ A1D) and (A1 A / AB) all equal (2 / Sq root (3)) = 1.155</span>
Let
x = base pay per month
y = commission per $1 of sales
Then the monthly pay for selling $100 of merchandise is
P = x + 100y
In one month, Alyssa earned $388 for selling $400 worth of merchandise.
Therefore
x + 400y = 388 (1)
In another month, she earned $520 for selling $1000 worth of merchandise.
Therefore
x + 1000y = 520 (2)
Subtract (1) from (2).
x + 1000y - (x + 400y) = 520 - 388
600y = 132
y = 0.22
From (1), obtain
x = 388 - 400y = 388 - 400*0.22 = 300
When Alyssa sells $3300 worth of merchandise, she earns
300 +0.22*3300 = $1026
Answer: $1026
