Question

Can someone help me with this ?

Answer 1

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
