Find the surface area of the cylinder. Use 3.14 for pi . a hay bale with a diameter of 30 inches and a height of 72 inches about

valentina_108 [34]

Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:

we are given:

Diameter of cylinder = 30 inches

Height of cylinder = 72 inches

We need to find:

Surface area of cylinder = ?

The formula used is:

$Surface\,\,Area=2\pi rh+2\pi r^2$

We know radius = diameter/2

so, radius = 30/2 = 15 inches

putting values:

$Surface\,\,Area=2\pi rh+2\pi r^2\\Surface\,\,Area=2*3.14*15*72+2*3.14*(15)^2\\Surface\,\,Area=6782.4+1413\\Surface\,\,Area=8195.4$

So, Surface Area of cylinder = 8195.4 inches^2

The vertex of a parabola is at (6,5), and its axis of symmetry is vertical. One of the x-intercepts is at (8, 0). What is the x-

Elena-2011 [213]

Answer:

$x=4$

Step-by-step explanation:

Vertex form of the quadratic equation: $f(x) = a(x - h)^2+k$

where the vertex is $(h, k)$

Given vertex = (6, 5):

$\implies f(x) = a(x - 6)^2+5$

If one the x-intercepts is (8, 0):

$\implies f(8) =0$

$\implies a(8 - 6)^2+5=0$

$\implies 4a+5=0$

$\implies a=-\dfrac{5}{4}$

Therefore, equation of parabola:

$\implies f(x) = -\dfrac54(x - 6)^2+5$

x-intercepts occur when f(x) = 0:

$\implies f(x)=0$

$\implies -\dfrac54(x - 6)^2+5=0$

$\implies -\dfrac54(x - 6)^2=-5$

$\implies (x - 6)^2=4$

$\implies x-6=\pm 2$

$\implies x=8, x=4$

Therefore, the x-coordinate of the other x-intercept is 4.

Apply the distributive property to factor out the greatest common factor.<br>55+35

Artyom0805 [142]

Answer:

Step-by-step explanation:

We have,

55 + 35

To find, the distributive property to factor out the greatest common factor,

55 + 35 = ?

We know that,

The distributive property of multiplycation,

The factors of 55 = 1, 5, 11 and 55 and

The factors of 35 = 1, 5, 7 and 35

The greatest common factor of 55 and 35 = 5

Using distributive property of multiplycation,

The greatest common factor = 5

Hence, the greatest common factor of 55 and 35 is .
