area of the circular sheet =22 cm²

answer for the given problem is given

Answer 2

Given:

• A circular sheet has radius=4 cm
• A circle of radius 3 cm is removed from the sheet.

To find:

• Area of the remaining sheet.

Solution :-

First in the circular sheet.

• Radius = 4 cm

As we know that in a circle

• ${\boxed{\bf Area={\pi} r^2}}$

Substitute the values :

${:}\longrightarrow\sf Area={\dfrac {22}{7}}\times (4)^2$

${:}\longrightarrow\sf Area={\dfrac {22}{7}}\times 16$

${:}\longrightarrow\sf Area=50.3\:cm^2$

Now in the removed circle .

• Radius = 3 cm

${:}\longrightarrow\sf Area={\pi}r^2$

${:}\longrightarrow\sf Area=\dfrac {22}{7}\times (3)^2$

${:}\longrightarrow\sf Area=\dfrac {22}{7}\times 9$

${:}\longrightarrow\sf Area=28.3\:cm^2$

Area of the remaining sheet = Area of circular sheet - Area of removed circle

${:}\longrightarrow\sf 50.3-28.3$

${:}\longrightarrow\sf 22cm^2$
