Answer:
Step-by-step explanation:
Given
--- big circle
--- area of small circle
Required
Probability that a point selected lands on the small circle
Calculate the area of the big circle using;
Where
So, we have:
This gives:
The probability that a point selected lands on the small circle is calculated by dividing the area of the small cicle by the big circle
This gives:
Simplify
7 hours
175 miles /25 miles per hour! = 7 hours
It depends if the one side is in between the angles or not.
The short answer is: when their fractions add up to full integers.
For examples, two halves make up a whole, or
so the mixed numbers with those will add up to full integers:
but if they don't add up to an interger, the whole sum won't be an integer:
Answer: the length of the prism is 9cm
Step-by-step explanation:
The formula for determining the volume of a rectangular prism is expressed as
Volume = length × height × width
Volume = LWH
The length of the rectangular prism is three times the width.. It means that
L = 3W
The height and the width are the same. This means that
H = W
Therefore,
Volume = 3W × × W × W = 3W³
If the volume of the prism is 81 cubic centimeters, it means that
81 = 3W³
Dividing through by 3, it becomes
81/3 = 3W³/3
W³ = 27
Taking cube root of both sides, it becomes
W = 3
Therefore, the the length of the prism would be
L = 3W = 3 × 3
L = 9 cm
