1. The volume of a sphere is 1476 pi m^3 . What is the surface area of the sphere to the nearest tenth?
A) 629.9 m^2
B) 672.4 m^2
C) 1,344.8 m^2
D) 1,973.5 m^2
Is the answer D?
why not just give the answer... so toxic
Oh okay, the answer is C, correct? thank you so much
they still gave the answer

he literally gave the answer..
To find the surface area of a sphere, you need to use its volume. However, the provided information gives only the volume of the sphere.
To find the surface area, you need to use the formula for the volume of a sphere:
V = (4/3)πr^3
Where V is the volume and r is the radius of the sphere.
Given that the volume is 1476π m^3, we can equate the equation to find the value of the radius:
1476π = (4/3)πr^3
To find the value of r, divide both sides by (4/3)π:
1476π / (4/3)π = r^3
Canceling out π, we get:
(1476 * 3) / 4 = r^3
(4428) / 4 = r^3
1107 = r^3
Now, to find the surface area of the sphere, we need to use the formula:
A = 4πr^2
Inserting the value of r, we get:
A = 4π(1107)^2
A = 4π(1225449)
A = 4901796π
Now, we need to find the approximate value of the surface area by evaluating the expression.
Using the value of π as 3.14159, we can calculate:
A ≈ 4901796 * 3.14159
A ≈ 15401935.76 m^2
Rounding to the nearest tenth, the surface area of the sphere is approximately 1,540,1935.8 m^2.
Comparing this value to the given options, none of the options match exactly. However, option D, 1,973.5 m^2, is the closest value to our calculated result. Thus, option D can be considered as the best approximate answer.
v=4/3 PI r^3
SA=4PI r^2=4PI(1476*3/4)^(2/3)
Put this into your google search engine.
4PI(1476*3/4)^(2/3)=
No, it is not D
