Mark as brainliest answer.
Step-by-step explanation:
→ Formula for curved surface area of cylinder = 2πrh
→ h = 10 cm
→ we have to find r = ?
→ 2πrh = 220
→ 2 × 22/7 × r/1 × 10/1 = 220
→ 440r/7 = 220/1
→ 440r(1) = (220)7
→ 440r = 1540
→ r = 1540/440
→ r = 3.5 cm
→ Now formula for volume of cylinder.= πr²h
→ 22/7 × 3.5/1 × 3.5/1 × 10/1
→ 2695/7
→ 385 cm³
