Answer:
r = 3.7 cm
Step-by-step explanation:
19.02 = 1/2π(2radius) + diameter
expanding:
19.02 = 1/2(3.14)(2r) + 2r
19.02 = 3.14r + 2r = 5.14r
r = 19.02/5.14 = 3.7 cm
$26.60 + $0.25t= $32.85
To Solve:
$26.60 + $0.25t= $32.85
$26.60 - $26.60+ $0.25t= $32.85 - $26.60
$0.25t = $6.25
$0.25t/$0.25 = $6.25/ $0.25
t= 25
Either c or d but most likely c
