Answer 1

Answer:

Y = 45 cm

Step-by-step explanation:

Given :-

• Radius of Cone = 28 cm
• Radius of cylinder = 15 cm
• Height of cylinder = 42 cm
• CSA of Cone = CSA of cylinder

Curved Surface Area of cylinder :-

CSA of Cylinder = 2πrh

CSA of Cylinder = 2×22/7×15×42

CSA of Cylinder = 2×22×15×6

CSA of Cylinder = 3960 cm²

Now,

As we know,

CSA of Cylinder = CSA of Cone

3960 = πry (y is the slant height)

3960 = 22/7 × 28 × y

3960 = 88 × y

3960/88 = y

y = 45 cm
