Answer 2

Step-by-step explanation:

Given:

A rectangular acrylic sheet is 36cm by 25cm. From it, 56 circular buttons, each of diameter 3.5cm have been cut out. Find the area of the remaining sheet

To find:

the area of the remaining sheet.

Solution:

Given: A rectangular acrylic sheet is 36cm by 25cm.

Remaining area = area of sheet −56 × area of 1 circular button

$= (36 \times 25) - 56 \times ( {\pir)}^{2} \\ = 900 - ( \frac{22}{7} \times \frac{3.5}{2} \times \frac{3.5}{2} ) \times 56 \\ = 900 - 539 \\ = 361 {cm}^{2}$

So, the area of the remaining sheet is 361cm².
