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

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}

So

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

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