C = 2(pi)r, where c is circumference, and r is radius.
The radius of a circle is half it's diameter. So, r = 36 cm / 2 = 18cm. r = 18cm.
Now, substitute the values in to the formula. c = 2(3.14)(18 cm) = 113.04 cm.

What is the area of the figure below?
-BARSIC- [3]

Answer:

54.8 = total area+

Step-by-step explanation:

Start with the widest part near the middle. Three inches is taken away from 7 inches to give 4 inches.

4 inches must be divided by 2 since the triangles so formed are congruent and there are 4 of them.

Use the Pythagorean theorem to get the height of the triangles. Solve the height for just one of them.

height = ??

Base = 2

hypotenuse = 5

height^2 + 2^2 = 5^2

height^2 + 4 = 25

height^2 + 4 - 4 = 25 - 4

height^2 = 21

height = sqrt(21)

height = 4.58

<em>Area of 4 Trangles</em>

Area of the triangles = 4 * (1/2 * 2 * 4.58)

Area of the triangles = 18.32

<em>Area of the Middle Rectangle</em>

Area = l * w

length = 4.58 * 2  where did that 2 come from?

width = 3

Area = 3 * 2 * 4.58

Area = 27.48

<em>Area of the two End Squares</em>

The end squares measure 3 by 3

Area square = s*s

The area = 3*3 = 9

<em>Total Area</em>

Area = 9 + 27.48 + 18.32

Area = 54.8 units.

The rectangle below has an area of x2 + 11x + 28 square meters and a length of 2 + 7 meters.
Troyanec [42]
<h3><u>Question:</u></h3>

The rectangle below has an Área of x^2 + 11x + 28 square meters and a length of x+7 meters. What expression represents the width of the rectangle?

<h3><u>Answer:</u></h3>

The expression representing width of rectangle is (x + 4) meters

<h3><u>Solution:</u></h3>

Given that rectangle has an area x^2 + 11x + 28 square meters and a length of x + 7 meters

To find: width of the rectangle

<em><u>The area of rectangle is given as:</u></em>

\text {Area of rectangle }=\text { length } \times \text { width }

Here area = x^2 + 11x + 28 square meters

length = x + 7 meters

<em><u>Substituting the values in given formula,</u></em>

\begin{array}{l}{\text { width }=\frac{x^{2}+11 x+28}{x+7}} \\\\ {\text { width }=\frac{x^{2}+4 x+7 x+28}{x+7}} \\\\ {\text { width }=\frac{x(x+4)+7(x+4)}{x+7}} \\\\ {\text { width }=\frac{(x+4)(x+7)}{x+7}}\end{array}

Cancelling (x + 7) on numerator and denominator,

\text { width }=(x+4)

Thus expression representing width of rectangle is (x + 4) meters

One angle of a triangle is 50 degrees greater than the smallest​ angle, and the third angle is 10 degrees less than twice the sm
tia_tia [17]
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.

Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10

50+x+x+2x-10=180
4x+40=180
4x=140
x=35

Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60

60+35+85=180
