Problem 1

Find the length of a square, where the area of the square is 9976014400 cm².

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of a square = a² So, the area of a square = 9976014400 cm² So, the length = √9976014400 = 99880. The length of each side = 99880 cm

Explanation

The length of a square is 99880 cm.

Because the area is 9976014400 cm², the length is √9976014400 = 99880.

Problem 2

Sara is planning to carpet her square room of length 99880 feet. The cost to carpet a square foot is 3 dollars. Then how much will it cost to carpet the full room?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The length of the room = 99880 feet The cost to carpet 1 square foot of room = 3 dollars. To find the total cost to carpet, we find the area of the room, Area of the room = area of the square = a² Here a = 99880 Therefore, the area of the room = 99880² = 99880 × 99880 = 9976014400. The cost to carpet the room = 9976014400 × 3 = 29928043200. The total cost = 29928043200 dollars

Explanation

To find the cost to carpet the room, we multiply the area of the room by cost to carpet per foot.

So, the total cost is 29928043200 dollars.

Problem 3

Find the area of a circle whose radius is 99880 meters.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of the circle = 31,348,970,624 m²

Explanation

The area of a circle = πr²

Here, r = 99880

Therefore, the area of the circle = π × 99880² = 3.14 × 99880 × 99880 = 31,348,970,624 m².

Problem 4

The area of the square is 9976014400 cm². Find the perimeter of the square.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The perimeter of the square is 399520 cm

Explanation

The area of the square = a²

Here, the area is 9976014400 cm²

The length of the side is √9976014400 = 99880

Perimeter of the square = 4a

Here, a = 99880

Therefore, the perimeter = 4 × 99880 = 399520.
