Vignesh owns a cottage in the shape of a cube with each edge of length 26 feet. The roof is in the shape of a square pyramid and
Zina [86]

Answer:

56√93 ≈ 540 ft²

Step-by-step explanation:

The roof is made up of 4 congruent isosceles triangles. Since the roof extends 2 ft over the edge of the cottage on each side, then the base of each triangle is 26 + 2 = 28 ft.

Let's calculate the area of one of the triangles and then just multiply by 4. See attachment. Drop a perpendicular from the vertex of a triangle to its base. We now have the triangle broken up into two right triangles. The hypotenuse is 17 ft and one of the legs of the right triangle is 28 / 2 = 14 ft. Then the height / other leg is:

\sqrt{17^2-14^2} =\sqrt{289-196} =\sqrt{93}

We now have the dimensions of each triangle: the height is √93 and the base is 28. The area of a triangle is: A = (1/2) * b * h, so we have the following.

A = (1/2) * b * h

A = (1/2) * 28 * √93 = 14√93

Multiply this by 4:

14√93 * 4 = 56√93

The total surface area is 56√93 ≈ 540 ft².

Please help I would love that!
Kazeer [188]

Answer:

Area= 7234.56

Step-by-step explanation:

area= πr²

diameter= 96

so that means radius is 48

48^{2} \pi= 7234.56

15. Evaluate the expression 13 ÷<br> (2.5-1-3).33.
OlgaM077 [116]

Evaluation of the expression using order of operation gives 26/11.

How to evaluate the expression

Given 13 ÷(2.5-1-3).33 =  13 ÷ 33( 2 x 5 - 1 - 3)

To evaluate this expression we need to apply the order of operation rule, BODMAS or PEMDAS.

13 ÷(2.5-1-3).33 =  13 ÷ 33( 2 x 5 - 1 - 3)  Evaluate multiplication

                         = 13 ÷ 33(10 - 1 - 3)        Evaluate what is in the bracket

                        =   13 ÷ 33(6)                  Evaluate division

                        = 13/33 x 6

                        = 78/ 33 = 26/11

Therefore, evaluating the expression gives 26/11.

Which angles form a linear pair?
Igoryamba

A linear pair of angles has a common side, and the vertex is on the line designated by the points denoting the non-common sides.

Consider the first choice:

... the common sided is RL, and the other two points are P and M. Point R (the vertex of the angles) is not on line PM. (In fact, line PM is not shown on the diagram.)

In the second choice, the given angles do not have a common side. (They are actually "vertical" angles.)

In the 3rd choice, the common side is RN, and vertex point R is found on line MO. These angles <em>are</em> a linear pair:

... - MRN and NRO
