answer : 54cm^2

pythagorus’ theorum : a^2 + b^2 = c^2

so 9^2 + x^2 = 15^2, x being the missing length

work out x ...

81 + x^2 = 225

x^2 = 144

x = 12

The volume of a cone is 3πx3 cubic units and its height is x units. Which expression represents the radius of the cone’s base, i

dalvyx [7]

Answer:

<em>r=3x</em>

Step-by-step explanation:

<u>The Volume of a Cone</u>

The volume of a cone of radius r and height h is:

$\displaystyle V=\frac{1}{3}\pi hr^2$

We are given the volume of a cone is

$V=3\pi x^3$

Equating:

$\displaystyle \frac{1}{3}\pi hr^2=3\pi x^3$

Multiplying by 3:

$\pi hr^2=9\pi x^3$

Simplifying by pi:

$hr^2=9 x^3$

Since h=x:

$xr^2=9 x^3$

Dividing by x:

$r^2=9 x^2$

Taking square roots:

$r=\sqrt{9 x^2}=3x$

Thus: r=3x

17/13 = y/10 solve for y and round to the nearest tenth

11Alexandr11 [23.1K]

$\frac{17}{13} = \frac{y}{10}$

$17 \times 10 = y \times 13$

$170 = 13y$

$y = \frac{170}{3} = 56.6666....$

56.6666... to the nearest tenth is <u>57</u>.
