Answer:
Length of the arc will be 2.69 cm.
Step-by-step explanation:
We have to calculate the length of an arc if θ = and radius of arc is 3 cm.
As we know length of an arc = r × θ
By putting the values of angle θ and radius of arc r in the formula
m (arc) = × 3
=
=
= 2.69 cm
Therefore, length of the arc will be 2.69 cm.

Answer:
yes. The cost of the insurance is less than the probability cost of the operation
Step-by-step explanation:
yes. The cost of the insurance is less than the probability cost of the operation
The cost of health insurance = $1200
Cost of dramatic injury operation= $500,000
chances of need of operation= 47.3% over a 20 years period
the amount of pay insurance after 20 years=
probable of cost operation= 0.473*500,00= $236,500
clearly the cost of insurance is less than the probable cost of operation.
