Answer 2

✰ Given :-

• 10 circular plates are placed on one another with ,Radius = 14 cm.
• Thickness of each plate = 3cm

✰ To find :-

• Volume of the new formed solid .

✰ How to do :-

• So, here in this question we have been given radius of each circular plate to be 14cm and thickness 3cm .Moreover ,it is given that these 10 plates are placed on one another .So the new formed solid is Cylinder ,with Radius = 14cm and Height = 30 cm ( 3 × 10=30)
• So,now we need to find the value of cylinder.

✰ Solution :-

Volume of cylinder = πr²h

➭ Volume = 22/7 × 14 × 14 × 30

➭ Volume = 18,480 cm³

∴,Volume of the solid = 18,480 cm³
