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
If there are 128 fluid ounces per US gallon, and there are 3 gallons, 3x128=384. The teacher brought 384 fluid ounces of juice on the feild trip.
we know that
Additive identity property:
If we add a real number to zero or add zero to a real number, then we get the same real number back.
The number zero is known as the identity element, or the additive identity.
For example: a+0 =a
we can see that adding gives same result
so, 0 is the additive identity here
