Find the value of x.<br> URGENT, please help!?

kotykmax [81]

Answer:

$x=\sqrt{30}$

Step-by-step explanation:

Use the geometric mean to solve for x. The side x is common to both the triangle that has the base of 3 and the triangle that has a base of 3 + 7, so x is the geometric mean. Set up that proportion as follows:

$\frac{3}{x}=\frac{x}{10}$ and

$x^2=30$ so

$x=\sqrt{30}$

Answer:

Step-by-step explanation:

Vol of a cylinder = pi * r^2 h

Vol of cone = 1/3 pi r^2 h

cylinder = pi * (1)^2 * (3) = 3 pi

cone = 1/3 pi (1^2) 4 = 4/3 pi

total = 3 pi + 4/3 pi

= pi(3+ 4/3) = pi(4.333)

= 13.6 f^3

The rec where katie works as a lifeguard has a rectangular diving pool. the diving pool is 4 meters deep and has a floor area of

wlad13 [49]

Answer:

The volume of the diving pool is $1400m^{3}$

Step-by-step explanation:

The volume of a rectangular pool is given by the following formula:

$V = S_{b}*h$

In which $S_{b}$ is the floor's area and h is the height.

The diving pool is 4 meters deep and has a floor area of 350 square meters.

This means that $h = 4m, S_{b} = 350m^{2}$

$V = S_{b}*h = 350m^{2}*4m = 1400m^{3}$

The volume of the diving pool is $1400m^{3}$
