The volume of a cylinder can is 1.54 litre and area of base is 77cm^2 Find its height

goblinko [34]

Answer:

The height is 20 cm.

Step-by-step explanation:

First, we have to know that the volume formula is V = πr²h and the base area of cylinder is a circle. So we can let πr² be 77 cm² . Then we have to substitute the following values into the formula :

$v = 1.54 \: l$

$v = 1540 \: {cm}^{3}$

$v = \pi \times {r}^{2} \times h$

Let πr² be 77,

Let v be 1540,

$1540 = 77 \times h$

$77h = 1540$

$h = 1540 \div 77$

$h = 20 \: cm$

which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3 ?

denis23 [38]

Answer:

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

Step-by-step explanation:

we know that

The equation of the line into point slope-form is equal to

$y-y1=m(x-x1)$

in this problem we have

$m=\frac{1}{3}$

$(x1,y1)=(3,2)$

substitute the values in the formula

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