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.

Help please !!! Need help
Answer:
234
Step-by-step explanation:
From the given information :
The 4th term, a4
a1 = 3
a2 = 4(a1) + 2
a2 = 4(3) + 2 = 14
a3 = 4(a2) + 2
a3 = 4(14) + 2
a3 = 58
a4 = 4a3 + 2
a4 = 4(58) + 2
a4 = 232 + 2
a4 = 234

What is the general form of a quadratic function?In Mathematics and Geometry, the general form of a quadratic function can be modeled and represented by using the following quadratic equation;
y = ax² + bx + c
Where:
a and b represents the coefficients of the first and second term in the quadratic function.c represents the constant term.Since the leading coefficient (value of a) in the given quadratic function f(x) = ax² + bx + c is positive 1/2, we can logically deduce that the parabola would open upward. Also, the value of the quadratic function f(x) would be minimum.

because the formula for the triangle is 1/2×b×h
and the formula for the rectangle nos l×w and then add those.
Answer:
A = 60yd
Step-by-step explanation:
First "separate" the rectangle and the triangle in your head.
Now calculate the area of the rectangle and then the area of the triangle.
Rectangle: 6*8 = 48
Triangle: (6*4)/2 = 24/2 = 12
Now we add them together:
48 + 12 = 60yd

Ms. Strickland is practicing the piano for an upcoming recital. The table list the number of minutes she practiced in the past few weeks.
a. What is the median number of minutes she practiced?
b.What is the range of the data?
c.What is the mean number of minutes that she practiced?
Answer:
a. 20
b. 32
c. 20.6
Step-by-step explanation:
Median is the middle number- so put the numbers in order from least to greatest, and find the middle number
8, 10, 10, 15, 15, 20, 20, 20, 25, 25, 25, 35, 40
Median is 20
the range is the difference between the largest and the smallest value- 40-8 is 32
Mean is the average- add all the values and divide by the total number of values (13)
268 minutes divided by 13 days
mean is about 20.6 minutes
