The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that rela

Sidana [21]

Answer:

k = 24, y = 24x

Step-by-step explanation:

Given x and y are proportional then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when y = 72, x = 3 , then

72 = 3k ( divide both sides by 3 )

k = 24

y = 24x ← equation of proportion

what is the surface area of cone with a diameter of 10 centimeters and a slant height of 12 centimeters round your answer to the

Oduvanchick [21]

The surface area of the cone is $266.9cm^2$

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

$r=\frac{d}{2} =\frac{10}{2} =5$

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

$S A=\pi r^{2}+\pi r l$

Substituting the values, we get,

$S A=(3.14)(5)^{2}+(3.14)(5)(12)$

$S A=(3.14)25+(3.14)(60)$

$SA=78.5+188.4$

$SA=266.9cm^2$

Thus, The surface area of the cone is $266.9cm^2$
