Question

A circle of radius 2 cm is cut out from a square piece of an aluminium sheet of side 6 cm.what is the area of the leftover aluminium sheet????​

Answer 1

Step-by-step explanation:

the question is solved in the above figure

Answer 2

$\LARGE\mathfrak\pink{answer}$

Explanation : To find the area of the leftover aluminium sheet, We want to find the area of the circle and the square, then subtract the area of circle form the area of the square.

Now let's do it!

First let's find the area of the square.

As we all know that the formula for finding the area of a square is side × side.

Area = side × side

Area = 6 × 6 = 36

Therefore, area of the square is $\large\sf\orange{36cm²}$

Now let's find the area of circle.

As we all know that the formula is $\pi$r².

Area = $\pi$r²

• Here we will take the value of pi as 22/7

Area = $\large\dfrac{22}{7}$ × 2 × 2

Area = $\large\dfrac{22}{7}$ × 4 = 12.57

Therefore, Area of the circle is $\large\sf\orange{12.57cm²}$

Now, let's find the area of the leftover aluminum sheet.

• As we said earlier we will subtract the area of the circle from the area of the square.

Area of the leftover aluminum sheet = 36 - 12.57

Area of the leftover aluminum sheet = 23.43

Therefore, Area of the leftover aluminum sheet is $\large\sf\orange{23.43cm²}$
