Answer:
$176
Expression: (12*3)+(70*2)
Step-by-step explanation:
The 3 hair brushes: $12*3= $36
The 2 hair straighteners: $70*2=$140
$140+$36=$176
Given:
Radius = 7cm
Central angle (theta) = 40 degrees
Asked:
Arc length (s)
SOLUTION:
s = 2*pi*radius*(central angle/360)
s = 2(3.14)(7cm)(40 degrees/360 degrees)
s = 4.88 cm
Therefore, the arc length of the circle is 4.88 centimeters.
