Hey ! there

Answer:

  • <u>Option </u><u>C </u><u>-</u><u> </u><u>7</u><u>2</u><u>.</u><u>2</u><u>2</u><u> </u><u>units </u>is the correct answer .

Step-by-step explanation:

In this question we are given with <u>diameter</u><u> of</u><u> circle</u><u> </u><u>that </u><u>is </u><u>2</u><u>3</u><u> </u><u>units </u><u>and </u><u>value </u><u>of </u><u>π </u><u>as </u><u>3.</u><u>1</u><u>4</u><u> </u><u>.</u><u> </u><u> </u> And We are asked to find the<u> </u><u>circumference</u><u> of</u><u> circle</u><u>. </u>

We know that ,

\qquad \qquad \:  \underline{\boxed{\frak{ Circumference = \pi d}}}

<u>Where </u><u>,</u>

  • π = <u>3.</u><u>1</u><u>4</u>

  • d = <u>diameter</u><u> </u><u>of</u><u> </u><u>circle</u>

<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u>

<u>\longrightarrow \qquad \: 3.14 \times 23</u>

By multiplying 23 with 3.14 we get :

\longrightarrow \qquad \:    \red{ \underline{\boxed{\frak{72.22}}}}

  • <u>Henceforth</u><u> </u><u>,</u><u> </u><u>circumference</u><u> </u><u>of </u><u>circle</u><u> </u><u>is </u><u>7</u><u>2</u><u>.</u><u>2</u><u>2</u><u> </u><u>units </u><u>.</u>

Answer:

The circumference of the circle is <u>C-72.22 </u><u>units</u>

Step by step explanation-

Given-

  • Diameter of circle (d) = 23 units
  • π = 3.14

Now,

<h3>\mathfrak {circumference \: of \: circle = \pi d }</h3>

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 3.14 \times 23

PSYCHO15rus [73]
Area of 1 exam room = 10 ft. × 10 ft. = 100 ft.²
Area of 10 exam room = 100 ft.² × 10 = 1000 ft.²

Area of waiting room = 20 ft. × 15 ft. = 300 ft.²

Area of office area = 25 ft. × 20 ft. = 500 ft.²

Now,
Total area of the hospital to be replaced = 1000 ft.² + 300 ft.² + 500 ft.² = 1800 ft.²

Select the two values of x that are roots of this equation.
PIT_PIT [208]

Answer:

x = 1 or -5/2

Step-by-step explanation:

-2x^2 - 3x + 5 = 0

multiply all through by -1

2x^2 + 3x - 5 = 0

....... 2x^2 × 5 = 10x^2 = +5x × -2x

(2x^2 + 5x)-(2x - 5) = 0

x(2x + 5) - 1(2x + 5) = 0

x - 1 = 0 or 2x + 5 = 0

x = 1 or 2x = - 5

x = 1 or -5/2
