Answer:
r = 22.9 in.
Step-by-step explanation:
Central angle in radians, ∅ = π/4
Length of arc, S = 18 in.
radius (r) = ?
Length of arc, C = r∅
Plug in the values and find r
18 = r*π/4
18 = (πr)/4
Multiply both sides by 4
4*18 = πr
72 = πr
Divide both sides by π
72/π = r
r = 22.9183118
r = 22.9 in. (Nearest tenth)
Odd question; there's no real rate exact 50 meters per lap (assuming the last is a typo), i.e we have a 50 meter pool.
d = 50 n
so when n=15
d = 50(15) = 750 meters
51
This answe is correct because u
