Question

from a circular sheet of radius 4 cm of a circle of radius 3 cm is removed find the area of remaining sheet . (take π = 3.14)​

Answer 1

Answer: 21.98

Step-by-step explanation:

As we cut it forms a ring and area of ring formula is π(R^2-r^2)

R= 4

r=3

π ( 4^2 - 3^2 )

π( 16-9)

π ( 7)

3.14 ×7

21.98 cm^2

Answer 2

$\huge\mathfrak{\underline{Correct\:question}}$

From a circular sheet of radius 4 cm, a circle of radius 3 cm is removed. Find the area of the remaining sheet. (Take π = 3.14)

_____________________________

Given that:-

• Radius of circularsheet = 4cm

• A circle of radius 3cm is removed.

To find:-

• The area of remaining sheet.

▪We have to take (π = 3.14).

Answer:-

$\bold{STEP-BY-STEP-EXPLANATION}$

From the question it is give that,

Radius of circular sheet R = 4 cm

A circle of radius to be removed r = 3 cm

Then,

The area of the remaining sheet = πR^2 – πr^2

= π (R2 – r2)

= 3.14 (42 – 32)

= 3.14 (16 – 9)

= 3.14 × 7

= 21.98 cm^2

So, the area of the remaining sheet is 21.98 cm^2.
