Answer:
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82

Answer:
Contract A is cheaper because $115 per month is less than $148 per month
Step-by-step explanation:
To find the unit price we divide the total cost given by the total months given for each contract to find out the cost per month.
$2070/18 months = $115 per month
$1776/12 months = $148 per month
Contract A is cheaper because $115 per month is less than $148 per month
