Answer:

Diameter = 24 mm

Step-by-step explanation:

Volume of a sphere is 4/3 π $r^{3}$

First, we solve for radius:

2304π = 4/3π $r^{3}$

Multiply both sides by 3

3(2304π) = 4π $r^{3}$

Divide both sides by 4π

6912π/4π = $r^{3}$

1728 = $r^{3}$

Cuberoot both sides

$\sqrt[3]{1728}$ = r

r= 12

Hence, the diameter would be: 2times the radius = 2*12= 24 mm

Hope this helps!

A fireplace arch is to be constructed in the form of a semiellipse. The opening is to have a height of 3 feet at the center and

USPshnik [31]

Answer:

Step-by-step explanation:

Given

Fireplace is in the form of semi-ellipse with height of 3 ft from center

Length of base=8 ft

if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis

2 a =8

a=4 ft

If contractor cover the whole base

then total length of string=2a =8 ft

(b)String should be nailed at focus

focus of ellipse is a e

where e=eccentricity

$e=\sqrt{1-(\frac{b}{a})^2}$

$e=\sqrt{1-(\frac{3}{4})^2}=\frac{\sqrt{7}}{4}$

Focus $=ae =\sqrt{7}$

Thus string should be nailed at 2.64 m from center

How to find arc measurements

joja [24]

Finding an arc length requires knowing a bit about the geometry of a circle. Since the arc is a portion of the circumference, if you know what portion of 360 degrees the arc’s central angle is, you can easily find the length of the arc.
