 \huge \underline \mathbb {SOLUTION:-}

Given:

  • Radius of 1st cylinder = 15cm
  • Height of 1st cylinder = 40 cm

  • Radius of 2nd cylinder = 20 cm
  • Height of 2nd cylinder = 45 cm

  • Also, height of new cylinder = 30 cm

ExPlanation:

Let the radius of new cylinder be r cm.

Sum of volumes of 1st and 2nd cylinder = volume of new cylinder

π × 152× 40 + π × 202× 45 = πr²× 30

⇒(225 × 40 + 400 × 45) = r² × 30

⇒ 9000 + 18000 = r² × 30

⇒27000 = r² × 30

⇒r² = 900

⇒r² = 302

r = 30 cm
