Answer:

The answer to your question is Volume = 12735.06 cm³

Step-by-step explanation:

Data

a = 11.26 cm

s = 13 cm

h = 29 cm

Formula

V = BH

Process

1.- Calculate the area of the base

Area = B = Pa/2

P = Perimeter

P = 6(13)

P = 78 cm

Area = (78)(11.26)/2

= 878.28/2

= 439.14 cm²

2.- Calculate the volume

Volume = BH

= (439.14)(29)

= 12735.06 cm³

Answer:

Correct answer: V = 12,733,17 cm³

Step-by-step explanation:

This is a regular six-sided prism.

Given:

The base edge a = 13 cm

Prism height H = 29 cm

The base of this prism is a regular hexagon consisting of six equilateral triangles.

The area of one equilateral triangle is:

A₁ = (a² · √3) / 4

Area of the base is:

B = 6 · A₁ = 6 · (a²· √3) / 4

B = 6 · (13² · √3) / 4 = 3 · 169 · √3 / 2 = 439.07 cm²

B = 439.07 cm²

The volume of the prism is:

V = B · H = 439.07 · 29 = 12,733,17 cm³

V = 12,733,17 cm³

What is the measure of ∠S ?

jeka94

Alright, lets get started.

We could use sine law to find the remaining angle.

$\frac{sinA}{a} = \frac{sinB}{b}$

$\frac{sinS}{63.6} = \frac{sin64}{69.8}$

Plugging the value of sin 64

$\frac{sinS}{63.6} = \frac{0.8987}{69.8}$

$\frac{sinS}{63.6} = 0.01287$

Cross multiplying

sin S = 0.8189

Taking inverse on both side

$S = sin^{-1}(0.8189)$

S = 55° : Answer

Hope it will help :)

Sally finds a coin with a radius of 1.5 centimeters and a thickness of 0.25 cm. It has a measured mass of 18.54 grams. How can S

mote1985 [20]

Answer:

Silver

Step-by-step explanation:

Find the volume of the coin

Volume of a cylinder

$\textsf{V}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}$

Given:

r = 1.5 cm
h = 0.25 cm

Substituting given values into the formula to find the volume:

$\sf \implies V=\pi (1.5)^2(0.25)$

$\sf \implies V=0.5625 \pi \:cm^3$

Find the density of the coin given it has a measured mass of 18.54 g

Density formula

$\sf \rho=\dfrac{m}{V}$

where:

$\rho$ = density
m = mass
V = volume

Given:

m = 18.54 g
$\sf V=0.5625 \pi \:cm^3$

Substituting given values into the density formula:

$\implies \sf \rho=\dfrac{18.54}{0.5625 \pi}$

$\implies \sf \rho=10.49149385\:g\:cm^{-3}$

Given:

$\textsf{Density of Lead}=\sf 11.3\:g\:cm^{-3}$

$\textsf{Density of Silver}=\sf 10.49\:g\:cm^{-3}$

Therefore, as $\sf \rho=10.49\:g\:cm^{-3}$ the coin is made from silver.
