A cylindrical glass is 3 inches in diameter and 6.5 inches tall. How much water can the glass hold when full? Round your answer

Vitek1552 [10]

3 inches diameter mean 1,5 in the radius
the height is 6,5 in.

volume of a cylinder = area of base time height

V= pir^2 *h

V = 3,14*1,5^2 *6,5

V = 45,92 in^3

What is the value of x?<br><br> sin55°=cosx<br><br> Enter your answer in the box.<br><br> x = <br> °

rodikova [14]

ANSWER

x=35°

EXPLANATION

The sine and cosine ratio are complementary trigonometric ratios.

This means that:

sin(A)°=cos(90-A)°

The given equation is:

sin(55)°=cos(x).

This implies that,

x=90-55

x=35°

The function gx is defined as gx=6x^2+23x-4,when does g(x)=0

VMariaS [17]

The given function is

$g(x) = 6x^2 +23x-4$

And we have to find the value of g(0), and for that we put 0 for x in the given equation.

And on substituting 0 for x in the given expression, we will get

$g(0) = 6(0)^2 +23(0) -4$

$g(0) = 0 + 0 -4 = -4$

So for the given function, the value of g(0) is -4 .

Find the equation for the circle with a diameter whose endpoints are (3,-1) and (-2,-1)

cricket20 [7]

Answer:

The equation for the circle is: $(x-\frac{1}{2} )^2 + y^2 = (\frac{5}{2} )^2$

Step-by-step explanation:

Here, let us assume the two end points of the diameter are:

P (3,-1) and Q (-2,-1)

Now, as we knew diameter is the chord that passer through the center of the circle.

⇒ Mid point of DIAMETER = Center coordinates of the Circle

Let us assume O(x,y) is the center of the line segment PQ.

So, by MID POINT FORMULA:

$(x,y)= (\frac{3 -2}{2} , \frac{-1-1}{2} ) =( \frac{1}{2},\frac{-2}{2}) \\\implies (x,y) =( 0.5 , -1)$

⇒ The center coordinates of the circle = O(0.5,-1) ...... (1)

Now, RADIUS = Half of DIAMETER

Using DISTANCE FORMULA:

$PQ = \sqrt{(3-(-2))^2 + (-1 - (-1))^2} = \sqrt{(5)^2 + 0} = 5$

So, Radius = 5/2 = 2.5 units

Now, the equation of circle with radius r and center coordinate ( h,k) is given as: $(x-h)^2 + (y-k)^2 = r^2$

Substitute r = 2.5 and (h,k) = (0.5,0) we get:

$(x-0.5)^2 + (y-0)^2 = (2.5)^2\\\implies (x-\frac{1}{2} )^2 + y^2 = (\frac{5}{2} )^2$

Hence the equation for the circle is: $(x-\frac{1}{2} )^2 + y^2 = (\frac{5}{2} )^2$
