Answer:
324π in²
Step-by-step explanation:
The surface area of a sphere = 4πr² ( r is the radius )
Calculate r using the volume (V) formula
V = πr³
Here V = 972π , thus
πr³ = 972π ( divide both sides by π )
r³ = 972 ( multiply both sides by 3 to clear the fraction )
4r³ = 2916 ( divide both sides by 4 )
r³ = 729 ( take the cube root of both sides )
r = = 9
Thus
surface area = 4π × 9² = 4π × 81 = 324π in²
The result of experiment in mixed fraction form is particles per milliliter.
To convert decimal to fraction, we the decimal number over 1 and multiply both the numerator and denominator by power of 10.
Given the data in the question;
In 117.755, we have 3 numbers to the right of the decimal point.
We have 10³ which is the same as 1000.
Next, we divide both the numerator and the denominator with their Greatest Common Factor.
Greatest Common Factor of 117755 and 1000 is 5
Now, we can get 200 out of 23551 exactly 117 times, since what remained is not divisible by 200, we leave it as a remainder [151].
We can now write this in a mixed fraction form as;
Therefore, the result of experiment in mixed fraction form is particles per milliliter.
