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

The base of a triangle is given as 2b. The height of the triangle is given as 5b-7. Find an expressions for the area of the tria

Tcecarenko [31]

Answer:

Step-by-step explanation:

Area = 1/2 * 2b * (5b - 7)

Area = 1/2 * 2b * (5b - 7) = 24

b * (5b - 7) = 24

5b^2 - 7b = 24

5b^2 - 7b - 24= 0

(b- 3 )(5b + 8) = 0

b = 3 This the only solution that works. b can't be minus

The base is 2b or 2 * 3 = 6
