The volume of this sphere is 904.32 cubic inches. What is the surface area of this sphere?
Use a 3.14 and round your answer to the nearest hundredth.
Answer:
A = 4 pi R^2 V = 4/3 pi R^3
A / V = 3 / R
Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in
So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2
The surface area of the sphere is S = 452.39 inches²
What is a Sphere?A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.
The Surface Area of a Sphere = 4πr²
The Volume of a Sphere = ( 4/3 ) πr³
where r is the radius of the sphere
Given data ,
Let the volume of the sphere be V = 904.32 inches³
Let the surface area of the sphere be S
And , Volume of a Sphere = ( 4/3 ) πr³
In this case, we are given that the volume of the sphere is 904.32 cubic inches, so we can set up an equation:
904.32 = (4/3)πr³
Solving for r:
r³ = (3/4) x (904.32 / π)
r ≈ 6.0 inches (rounded to one decimal place)
Now that we know the radius, we can use the formula for the surface area of a sphere:
A = 4πr²
Plugging in the value of r:
A = 4 x 3.14 x 6.0²
A ≈ 452.39 inches² (rounded to two decimal places)
Hence , the surface area of the sphere is approximately 452.39 square inches.

Answer:

A can do a piece of work in 10 days, B in 12 days and C in 15 days. How long will it take them it together to complete it ?
Explanation -:We observe here that A can do the work in 10 days; B can do the same work in 12 days whereas C can do the same work in 15 days. We are asked to calculate how much time will it take if three of them will work together.
We will solve this problem with traditional method.
Let us solve the question.

Option C is the only table that represents a data set that could be fit to a normal distribution curve.
In a normal distribution, the data is symmetrically distributed around the mean, and the percentages decrease as you move away from the mean.
Option C exhibits this characteristic, where the percentages are highest at the mean values (5, 6, 9, 10) and decrease as you move away from the mean.
Where as the tables in options A, B, and D do not exhibit the characteristics of a normal distribution as the percentages do not decrease symmetrically away from the mean values.

In ΔNOP, n = 800 inches, ∠P=97° and ∠N=32°. Find the length of o, to the nearest inch.
9514 1404 393
Answer:
1173 in
Step-by-step explanation:
The measure of angle O is ...
O = 180° -N -P = 180° -32° -97° = 51°
The law of sines tells you ...
o/sin(O) = n/sin(N)
o = n·sin(O)/sin(N) = (800 in)·sin(51°)/sin(32°)
o ≈ 1173 in

if -2x+ y =6 and -7x-4y=-8 are true equations what would the value of -9x-3y
Answer:
[tex]-\frac{106}{5} or -21.2[/tex]
Step-by-step explanation:
First we would have to get x and y-values by solving systems of equations:
isolate one of the variable from any of the first 2 equations given:
-2x+ y =6 would be y = 2x + 6 when y is isolated.
now plug this equation in for the y given in the second equation:
-7x -4(2x + 6) = -8
Now solve to get the x-value,
-7x - 8x - 24 = -8
-15x - 24 = -8
-15x = 16
x = [tex]-\frac{16}{15}[/tex] or -1.06
To solve for y-value, substitute the gotten x-value in any of the 2 equations and solve:
y = 2([tex]-\frac{16}{15}[/tex]) + 6
y = [tex]\frac{58}{15}[/tex] or 3.86
Now that we have the x and y-values, substitute them in for the 3 equation given:
-9([tex]-\frac{16}{15}[/tex]) -3( [tex]\frac{58}{15}[/tex])
=> [tex]-\frac{106}{5}[/tex] or -21.2 = Final Answer

The sum of the fifth and sixth term of an AP is 30.If the third term is 5.Find the first term.
Answer:
The first term is -3.
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.
The nth term is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term.
If we have the mth term instead of the first, we have:
[tex]a_n = a_m + (n-m)d[/tex]
We have the third term, and need the fifth and the sixth:
So we write both the fifth and the sixth in function of the third, then:
[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]
[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]
The sum of the fifth and sixth term of an AP is 30
We use this to find [tex]d[/tex]. So
[tex]a_5 + a_6 = 30[/tex]
[tex]5 + 2d + 5 + 3d = 30[/tex]
[tex]5d + 10 = 30[/tex]
[tex]5d = 20[/tex]
[tex]d = \frac{20}{5} = 4[/tex]
First term:
The third term is:
[tex]a_3 = a_1 + 2d[/tex]
Since [tex]a_3 = 5, d = 4[/tex]
[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]
The first term is -3.
