Question

from asquare sheet of side 15cm, acircle of radius 7 cm is cut out. calculate the remaining sheet after the circle is removed​

Answer 1

Given :-

• Side of square sheet is 15cm.
• Radius of the circle is 7cm.

⠀

To find :-

• Remaining sheet after the circle is removed.

⠀

Solution :-

• In this question we have side of square sheet and radius of the circle that is cutted out of the sheet.

⠀

Firstly, we need to find the total area of the sheet.

Since the sheet is in the shape of square.

⠀

★ Area = Side × Side

⠀

→ Area = 15 × 15

→ Area = 225 cm²

⠀

Now, we will calculate the area of the circle that is cut out from the sheet.

⠀

★ Area = πr²

⠀

→ Area = 22/7 × 7 × 7

→ Area = 22 × 7

→ Area = 154 cm²

⠀

For calculating the area of remaining sheet, we have to subtract the area of circle from the area of the sheet.

⠀

→ Remaining sheet = 225 - 154

→ Remaining sheet = 71 cm²

⠀

Hence,

• The area of the remaining sheet is 71 cm².
