What is the area of the square adjacent to the third side of the triangle?
lana66690 [7]

Answer:

The area of the square adjacent to the third side of the triangle is 11 units²

Step-by-step explanation:

We are given the area of two squares, one being 33 units² the other 44 units². A square is present with all sides being equal, and hence the length of the square present with an area of 33 units² say, should be x² = 33 - if x = the length of one side. Let's make it so that this side belongs to the side of the triangle, to our convenience,

x² = 33,

x = \sqrt{33} .... this is the length of the square, but also a leg of the triangle. Let's calculate the length of the square present with an area of 44 units². This would also be the hypotenuse of the triangle.

x² = 44,

x = \sqrt{44} .... applying pythagorean theorem we should receive the length of a side of the unknown square area. By taking this length to the power of two, we can calculate the square's area, and hence get our solution.

Let x = the length of the side of the unknown square's area -

\sqrt{(44)}^2 = x^2 + \sqrt{33}^2,

x = \sqrt{11} ... And \sqrt{11} squared is 11, making the area of this square 11 units².

What is the area and circumference of the circle (3.14 for pi)
nasty-shy [4]

We will use the proper formula and solve.

    -> A diameter of 48 / 2 = 24 feet as our radius

   Area:

A = πr²

A = (3.14)(24)²

A = 1,808.64 ft²

      The circle has an area of about 1,808.64 ft²

   Circumference:

C = 2πr

C = 2(3.14)(24)

C = 150.72 ft

      The circle has a circumference of about 150.72 ft
