Question

From a circular sheet of radius 4 cm, a circle of radius 3 cm is cut out. Calculate the area of the remaining sheet after the smaller circle is removed.

Anyone who gives the correct answer will definitely be marked as brainliest

Answer 1

Answer:

it is

area of large circle - area of small circle

that is

π×16 - π×9 = 7π is the req answer

Answer 2

Answer:

88.7264cm²

Step-by-step explanation

Area of the remaining sheet = area of the circular sheet - area of the cut-out sheet

Area of a circle = (Pi × radius)²

For the area of the circular sheet,

Let's take Pi = 3.14

Therefore,

Area of the sheet = (3.14 × 4)² = 242.0136

For the area of the cut-out sheet,

Let's take Pi = 3.14

Therefore,

Area of the sheet = (3.14 × 3)² = 88.7264

SO, THE AREA OF THE REMAINING SHEET = 242.0136 - 88.7264 = 159.2972
