Question

From a circular sheet of radius 4cm a circle of radius 3cm is removed. Find the area of the remaining sheet.

Answer 1

Here is your answer...

r=3cm

R=4cm

ar.(remaining sheet)=πR²—πr²

=22/7×4×4-22/7×3×3

=22cm²

Hope it helps...

Answer 2

Given:-

• Radius of Big Circle = 4cm
• Radius of Small Circle = 3cm

To find:-

• The area of Remaining Sheet.

Solution:-

Radius of Big circle = 4 cm

Area of Bigger Circle = πr²

= 3.14 × 4 × 4

= 50.24 cm²

Area of Small Circle = 3cm

Area of small circle = πr²

= 3.14 × 3 × 3

= 28.26 cm²

Area of Remaining Sheet = Area of Big Circle

= Area of small Circle

= 50.24 - 28.26cm

= 21.98 cm²

Hence, Answer is 21.98 cm² of Remaining Sheet
