SCALE
60 cm
Calculate the volume of water needed to fill the tank
Answers
Answer:
a) The volume of the sphere is approximately 14,137.16694 which is 14,140 cm³ correct to 4 significant figures
b) The volume of water required to fill the tank is approximately 103,670 cm³
Step-by-step explanation:
a) In the question, the radius of the sphere, r = 15 cm
The formula for the volume, 'V', of a sphere is given as follows;
[tex]V = \dfrac{4}{3} \times \pi \times r^3[/tex]
Where;
r = The radius of the the sphere
V = The volume of the sphere
Plugging in the value for the radius, 'r', of the sphere, in the equation for, 'V', we get;
[tex]V = \dfrac{4}{3} \times \pi \times 15^3 \approx = 14,137.16694[/tex]
Therefore;
The volume of the sphere to 4 significant figures is V ≈ 14,140 cm³
b) The parameters of the cylindrical tank are;
The height of the cylindrical tank, h = 60 cm
The radius of the cylindrical tank, r = 25 cm
The volume of a cylinder, V = π·r²·h
∴ The volume of the cylindrical tank without water, '[tex]V_t[/tex]', is given as follows;
[tex]V_t[/tex] = π × (25 cm)² × 60 cm ≈ 117809.72451 cm³
The volume of water, [tex]V_{water}[/tex], required to fill the tank with the sphere of volume 'V' placed inside is given as follows
[tex]V_t[/tex] = V + [tex]V_{water}[/tex]
∴ [tex]V_{water}[/tex] = [tex]V_t[/tex] - V
From which we get;
[tex]V_{water}[/tex] ≈ 117809.72451 cm³ - 14,140 cm³ = 103,669.72451 cm³ ≈ 103,670 cm³
The volume of water required to fill the tank, [tex]V_{water}[/tex] ≈ 103,670 cm³.

Loki wrote 1/6 of a page in 1/12 of a minute. How much time does it take him to write a full page?
Answers
EXPLANATION:
To find the answer, we can find an equivalent fraction for each.
1/6 x 6 = 6/6
1/12 x 6 = 6/12
So every 1 minute Loki writes half a page.
Since 2 halves = 1.
2 minutes for 1 page.

If the sum of the measures of the interior angles of a polygon is 1920°, how many sides does it have? math
Answers
Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-
[tex](n-2)\times180^{\circ}[/tex]
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]
[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Annie wants to eat an entire donut. However, since she only two-years-old, the mother says she can
only have a third of the donut. If the diameter of the donut is 4 inches, how long is the outside edge of
the piece that Annie gets to eat? Round your answer to the nearest hundredth of an inch.
Answers
Answer:
4.19 inches
Step-by-step explanation:
Your goal is to find the circumference of the donut and then divide that by 3 to get 1/3 of the outer edge of the donut.
Circumference is 2[tex]\pi[/tex]r
The diameter (double the radius) is 4, so radius (r) is 2
2 * pi * 2 = 4 pi = 12.57 (round to hundredth)
12.57/3 = 4.19
keep in mind that dividing by 3 is the same as multiplying by 1/3

The graph of the function g(x) is a transformation of the parent function f(x)=x2. Which equation describes the function g?
1. g(x)=(x−4)2
2.g(x)=x2+4
3.g(x)=x2−4
4.g(x)=(x+4)2
Answers
Answer:
g(x) = x^2 - 4 (Answer #3)
Step-by-step explanation:
The graph of the parent function f(x) = x^2 is a parabola with vertex at (0, 0). That of g(x) is the same, except that the first graph has been translated down by 4 units.
When this happens, the original function f(x) = x^2 + 0 changes to
g(x) = x^2 - 4 (Answer #3)
