Answer:

5.0 cm

Step-by-step explanation:

Volume of a cylinder = πr²h

Height,h = 12.75 cm

π = 3.14

Radius,r = r

Volume of the cylinder = 1,000 cm³

Volume of a cylinder = πr²h

1000 = 3.14 × r² × 12.75

1000 = 40.035r²

r² = 1000/40.035

r² = 24.978

r = √24.978

r = 4.99 cm

Approximately 5.0 cm
