if the diameter is 4 units, then its radius is half that, or 2.

\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ \cline{1-1} r= 2 \end{cases}\implies A=\pi 2^2\implies A=4\pi \implies \stackrel{\pi =3.14~\hfill }{A\approx 12.57}

Answer:

12.6 ft²

Step-by-step explanation:

The formula for the area of a circle is

A = πr²

If d = 4 ft,

   r = 2 ft

  A = 3.14 × 2² = 3.14 × 4 = 12.6 ft²

Answer:

c. Rational

because → whole numbers are positive and Starts from 0 so not whole number

Integers can be negative and positive

Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.

Irrational number that cannot be written in p/q

but -2.4 written in p/q = -24/100

<h3>so c. Rational Number is correct</h3>

The length of a rectangle is 5 less than twice the width. If the perimeter of the rectangle is 146 cm, find the dimensions of th
Marta_Voda [28]

Length = 2x - 5

Width = x

Perimeter = 146

P = 2L + 2W

146 = 2(2x - 5) + 2x

146 = 4x - 10 + 2x

146 = 6x - 10

146 + 10 = 6x

156 = 6x

156/6 = x

26 = x

Length = 2(26) - 5

Length = 52 - 5

Length = 47 cm

Width = x

Width = 26 cm

Find inverse of y=1/2x+3
yKpoI14uk [10]

Answer:  f⁻¹(x)=2x-6

Step-by-step explanation:

To find the inverse of an equation, you replace y with x and x with y. Then, you solve for y.

y=1/2x+3          [replace y with x and x with y]

x=1/2y+3          [subtract both sides by 3]

x-3=1/2y           [multiply both sides by 2]

y=2(x-3)            [distribute]

y=2x-6

Now, we know the inverse function is f⁻¹(x)=2x-6.

4(x−3)≥56=<br> Please helppppp
pickupchik [31]

Answer:x≥17

Step-by-step explanation:

Let's solve your inequality step-by-step.

4(x−3)≥56

Step 1: Simplify both sides of the inequality.

4x−12≥56

Step 2: Add 12 to both sides.

4x−12+12≥56+12

4x≥68

Step 3: Divide both sides by 4.

4x4≥6

8

4

x≥17
