Question

Find the volume of cylinder if redius -7 cm and height -10 cm
​

Answer 1

Given

• Radius (r) = 7 cm
• Height (h) = 10 cm

To find

• Volume (v) of cylinder

Solution

• Volume of cylinder = πr²h
• Volume = 22/7 × 7 × 7 × 10
• Volume = 1540

∴ Volume of the cylinder = 1540 cm³

• Total surface area of cylinder = 2πr(r+h)
• Curved surface area of cylinder = 2πrh
• The value of radius and height can never be negative (-)

Answer 2

Step-by-step explanation:

GIVEN

We are given a cylinder which has

1. radius : 7cm
2. height : 10cm

TO FIND

Volume of the cylinder

We know that volume of a cylinder is given by the formula

V = π r^2 h

SOLUTION

In the last step , we need to plug in the values of radius and height mentioned in the question

V = π × 49 × 10

Volume of the given cylinder = 490π

Or , Volume = 22/7 × 490 = 1540 cm^3

Here we should be clear about the fact that length can never be negative.
