Answer 2

✠ Given :-

• Volume of cone = 210 cm³
• Height of the cone = 14 cm

----------------------------------------------------

✠ To Find :-

• Radius of the cone

----------------------------------------------------

✠ Solution :-

★ Volume of the cone = ⅓πr²h

⇒ 210 = ⅓ × 22/7 × r² × 14

⇒ 210 × 3 = r² × 44

⇒ 630 = r² × 44

⇒ r² = 630/44

⇒ r = √14.31 cm
