The formula for the volume of a cylinder is V= a X h
Where a is the are of base and h is height. The base is a circle, so a= pi r^2
471=3.14 (r^2)(6) Divide both sides by 6, then 3.14
25 =r^2 Your next step would be to find the square root of 25
5=r Now you know the radius of the circle, but it asks for diameter. The radius is half of the diameter, so 5 X 2= 10. Your answer would be 10

V= pi * r^2 * h
471 = 3.14 * r^2 *6
471 = 18.84 * r^2
25 = r^2
Sqrt25 = r
5 = r
D= 2*5
D= 10in

Max built a rectangular Prism and a rectangular Pyramid using beach sand. The prism and the pyramid have the same base area and

vova2212 [387]

Answer:

Three times

Step-by-step explanation:

Given

Figures: Rectangular Prism and Rectangular Pyramid

Let the dimension of the prism be:

$l = length$

$w = width$

$h = height$

Amount of sand used is the volume (V1) and it is calculated using;

$V_1 = l * w * h$

$V_1 = lw h$

Since the pyramid has the same base area and height as the prism, the its dimension would be:

$l = length$

$w = width$

$h = height$

Amount of sand used is the volume (V2) and it is calculated using;

$V_2 = \frac{1}{3}*(lwh)$

So, we have:

$V_1 = lw h$

$V_2 = \frac{1}{3}*(lwh)$

Substitute lwh for V1 in the second equation

$V_2 = \frac{1}{3}V_1$

Multiply both sides by 3

$3 * V_2 = \frac{1}{3}V_1 * 3$

$3 * V_2 = V_1$

Reorder

$V_1 = 3 * V_2$

$V_1 = 3 V_2$

<em>Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid</em>
