Can someone help me with this ?

Answer:
11 inches
Step-by-step explanation:
We want to work out the radius of the cylinder in inches so we have to utilise the volume of a cylinder formula which is
Volume = π × r² × h
Where "r" is the radius and "h" is the height
→ First substitute the value into the formula
121 π = π × r² × 1
→ We can divide both sides by π to get rid of it
121 = r² × 1
→ We should divide both sides by 1 to isolate r²
121 = r²
→ Now, we can square root both sides to find the value of the radius
11 = r
→ So the radius of the cylinder is 11 inches
