The appropriate choice is ...
A. 3 radians
_____
Arc length (s) is given in terms of radius (r) and central angle (θ) in radians by the formula
s = rθ
When you substitute your given information, you have
3r = rθ
Dividing by r gives
θ = 3 . . . . . . . radians
=1/2* r^2 * theta
r=D/2=3 cm
theta=110 deg= 1.92 radian.
area=1/2*3*3*1.92 cm2 =8.64 cm2
=8.6 cm2 (approx.)
Answer:
The cost of maintenance and repairs is $235
Step-by-step explanation:
step 1
Find the market values of car for age of car equal to 7 year
Observing the graph
The percentage of market value is 10%
so
10%=10/100=0.10
The market value is equal to
$23,500*0.10=$2,350
step 2
Find the cost of maintenance and repairs for age of car equal to 7 year
Observing the graph
The percentage of maintenance and repairs of car's value is 10%
so
10%=10/100=0.10
The cost of maintenance and repairs is
$2,350*0.10=$235
