Answer:
8.565
Step-by-step explanation:
Volume=4/3pir^3
3000m^3=4/3pir^3
3000/4/3=pir^3
25/pi=r^3
approx 78.539=r^3
r=4.2825
we know,
2r=d
d=2×4.2825
d=8.565
You can round the answer off yourself :3
converted to fraction in lowest terms is 
<em><u>Solution:</u></em>
Given that we have to convert
to fraction in lowest terms
Let us first convert the mixed fraction 
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator.
Therefore,


Now convert 77.5 % to fraction
So we have to convert percentage to fraction
Divide the percentage by 100 to get a decimal number

Use that decimal number as the numerator of a fraction. Put a 1 in the denominator of the fraction
Count the number of places to the right of the decimal. If you have x decimal places then multiply numerator and denominator by 

Simplify and reduce the fraction to lowest terms

Thus the given percentage is converted to fraction in lowest terms
