Answer:
r = 6
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Given A = 36π , then
πr² = 36π ( divide both sides by π )
r² = 36 ( take the square root of both sides )
r = = 6
6
A = π. r²
36π = π. r²
eliminate π, we get:
36=r²
r=√36
Given the problem, I believe your answer would be:
h(3)=144
h=48
Hope this helps!
the answer is 45
