Problem 1

Find the length of a square where the area of the square is 7,990,276 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 7,990,276 cm²

So, the length = √7,990,276 = 2826.

The length of each side = 2826 cm

Explanation

The length of a square is 2826 cm.

Because the area is 7,990,276 cm², the length is √7,990,276 = 2826.

Problem 2

Samantha is planning to tile her square floor with sides of 2826 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the entire floor?

Okay, lets begin

The length of the floor = 2826 feet

The cost to tile 1 square foot of floor = 5 dollars.

To find the total cost to tile, we find the area of the floor,

Area of the floor = area of the square = a²

Here a = 2826

Therefore, the area of the floor = 2826² = 2826 × 2826 = 7,990,276.

The cost to tile the floor = 7,990,276 × 5 = 39,951,380 dollars.

The total cost = 39,951,380 dollars

Explanation

To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.

So, the total cost is 39,951,380 dollars.

Problem 3

Find the area of a circle whose radius is 2826 meters.

Okay, lets begin

The area of the circle = 25,104,314.64 m²

Explanation

The area of a circle = πr²

Here, r = 2826

Therefore, the area of the circle = π × 2826² = 3.14 × 2826 × 2826 = 25,104,314.64 m².

The area of the square is 7,990,276 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 11,304 cm.

Explanation

The area of the square = a²

Here, the area is 7,990,276 cm²

The length of the side is √7,990,276 = 2826

Perimeter of the square = 4a

Here, a = 2826

Therefore, the perimeter = 4 × 2826 = 11,304 cm.
