The value of the radius is 2.62.
Given,
258.75=3.14r²12.
We need to find the radius from this expression.
It is given by:
V = [tex]\pi[/tex] r² h
Where r is the radius and h is the height.
Write the given expression
258.75=3.14r²12
This can be compared with the volume of a cylinder
V = [tex]\pi[/tex] r² h
V = 258.75
[tex]\pi[/tex] = 3.15
r²
h = 12
Find r.
258.75=3.14r²12.
r² = 258.75 / 3.14 x 12
= 6.86703
r = square root 6.86703
r = 2.62
Thus the value of the radius is 2.62.
