One circular table has a diameter of 8 ft, and another circular table has a diameter of 12 ft. How much greater is the area of t
he larger table?
2 answers:
Answer:
20π sq ft ≈ 62.83 sq ft
Step-by-step explanation:
Area of table with diameter 8 ft = π*8^2/4 = 16π
Area of table with diameter 12 ft = π*12^2/4 = 36π
Difference between the area of the tables ;
= 36π - 16π
= 20π sq ft ≈ 62.83 sq ft ( π = 3.14)
Answer:
62.83
Step-by-step explanation:
First, you have to find the area of both using the area formula for a circle:
<em>A = </em>
Radius is half of the diameter:
<em>A</em><em> = </em>(3.1415926535...)( ) <em>A</em><em> = </em>(3.14159265...)( )
A ≈ 50.265... A ≈ 113.097...
How much greater:
A - A ≈ 62.83185

In Binomial distribution, the expected value or mean is given by,
E(X) = np
where, p = probability of success and n=number of sample size.
E(X) = 100×0.4 = 40
