Answer:

153.94

Step-by-step explanation:

c=2r*r

The radius is half of the diameter.

To find the radius you will divide 49 inches by 2.

You should get a total of 24.5

Now that you have your radius you are going to use the circumference formula to solve.

C= 2r*r

C=2(24.5)*(24.5)

type that into the calculator (without the parenthesis) and boom your done!

You answer should be 153.938

then you round to get a total of 153.94

I hope i was able to help!

Answer: c = 3771.481981 (decimal place) or 1200.5 $\pi$ (exact form)

Step-by-step explanation:

c = 2 $\pi$ r

c = 2 x $\pi$ x $24.5^{2}$

radius = diameter divided by 2

= 49 divided by 2

= 24.5

c = 3771.481981 (decimal place) or 1200.5 $\pi$ (exact form)

Y = 3(x-2)^2 + 5

Orlov [11]

The y-intercept coordinate is at the point (0, 17)

<h3>Properties of functions</h3>

Given the following function expressed as:

$y = 3(x-2)^2 + 5$

The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
Domain are the input values for which the function exist. According to the function, the domain and range exists on all real values

The x-intercept is the point where y = 0

$3(x-2)^2 + 5=0\\3(x-2)^2 = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}$

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

$y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17$

The y-intercept coordinate is at the point (0, 17)

Answer:

x = 3.6

Step-by-step explanation:

1 (4) = 4

0.9 (4) = 3.6

x = 3.6

There is a sequence... adding 0.9 to each side (at different lengths).

What is the volume of a cone with a radius of 4 and a height of 15?

Pie

Answer:

A. 251.33 cubic units

Step-by-step explanation:

volume of cone = (1/3) * area of base * height

Since your base is a circle, the area of the base is pi * r^2.

Now we have

volume of cone = (1/3) * pi * r^2 * h

volume of cone = (1/3) * 3.14159 * 4^2 * 15

volume of cone = 251.33 cubic units
