Find the radius of a sphere with a surface area of $4\pi$ square feet.
1 answer:
Answer:
r = 1 feet
Step-by-step explanation:
Given that,
The surface area of the sphere, A = 4π feet²
We need to find the radius of the sphere.
The formula for the surface area of the sphere is given by :
Where
r is the radius of the sphere
Put all the values,
So, the radius of the sphere is equal to 1 feet.

Answer:
Three Times.
Step-by-step explanation:
First and foremost a binary search requires that the array be sorted in ascending or descending order.
After the initial step the search goes to the middle most value
i.e.
will be the second 14, which is the first iteration.
Since 14 is less than 19 the search will eliminate the lower half of the including 14, and will iterate again through the array:
The array will go to the middle most value which is 18, second iteration. Since 18 is less than 19, the program will eliminate the lower half and be left with two values i.e. .
The search will run once i.e. third iteration, and will return key value found.
