Problem 1

Find the length of the square, where the area of the square is 100020001 cm².

Okay, lets begin

The area of a square = a² So, the area of a square = 100020001 cm² So, the length = √100020001 = 10001. The length of each side = 10001 cm

Explanation

The length of a square is 10001 cm.

Because the area is 100020001 cm² the length is √100020001 = 10001.

Problem 2

Anna is planning to paint her square wall of length 10001 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 10001 feet The cost to paint 1 square foot of wall = 3 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 10001 Therefore, the area of the wall = 10001² = 10001 × 10001 = 100020001. The cost to paint the wall = 100020001 × 3 = 300060003. The total cost = 300060003 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot.

So, the total cost is 300060003 dollars.

Problem 3

Find the area of a circle whose radius is 10001 meters.

Okay, lets begin

The area of the circle = 314187957.3 m²

Explanation

The area of a circle = πr²

Here, r = 10001

Therefore, the area of the circle = π × 10001² = 3.14 × 10001 × 10001 = 314187957.3 m².

Problem 4

The area of the square is 100020001 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 40004 cm.

Explanation

The area of the square = a²

Here, the area is 100020001 cm²

The length of the side is √100020001 = 10001

Perimeter of the square = 4a

Here, a = 10001

Therefore, the perimeter = 4 × 10001 = 40004 cm.
