Question

A cylinder is 6cm tall and has a circular base with 7cm radius.So its lateral surface area will be​

Answer 1

Step-by-step explanation:

Answer

radius (r)=6 cm, height (h)=7 cm.

Volume of a right circular cylinder (V)

=πr

2

h

=

7

22

×6×6×7

=792 cm

3

∴ Volume of a cylinder =792 cm

Answer 2

Correct Question :-

• The radius of the base of a right circular cylinder is 6 cm and height is 7 cm. Find the volume.

Given :-

• Base = 6cm
• Height = 7cm

To Find :-

• The Volume of Cylinder

Solution :-

⇒ Volume of Cylinder = πr²h

⇒ Volume of Cylinder = 22/7 × (6)² × 7

⇒ Volume of Cylinder = 22/7 × 6 × 6 × 7

⇒ Volume of Cylinder = 22 × 6 × 6

⇒ Volume of Cylinder = 132 × 6

⇒ Volume of Cylinder = 792cm³

________________

Therefore, Volume of Cylinder is 792cm³

★ Additional Info :

• Volume of cylinder = πr²h
• T.S.A of cylinder = 2πrh + 2πr²
