Problem 1

Find the length of the square, where the area of the square is 743,044 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 743,044 cm²

So, the length = √743,044 = 862.

The length of each side = 862 cm

Explanation

The length of a square is 862 cm. Because the area is 743,044 cm², the length is √743,044 = 862.

Problem 2

Sarah is planning to tile her square kitchen floor of length 862 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 862 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 = 862

Therefore, the area of the floor = 862² = 862 × 862 = 743,044.

The cost to tile the floor = 743,044 × 5 = 3,715,220.

The total cost = 3,715,220 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 3,715,220 dollars.

Problem 3

Find the area of a circle whose radius is 862 meters.

Okay, lets begin

The area of the circle = 2,334,198.36 m²

Explanation

The area of a circle = πr²

Here, r = 862

Therefore, the area of the circle = π × 862² = 3.14 × 862 × 862 = 2,334,198.36 m².
