To solve this problem and calculate the area of the sphere, you must apply the following formulas:
Formula N° 1:
V=4/3(πr³)
V is the volume of the sphere (V=3,000π m³).
r is the radius.
Formula N° 2:
A=4πr²
A is the area of the sphere.
r is the radius.
As you can see, you don't have the value of the radius "r". So, you must rewrite the Formula N° 1, and clear "r":
V=4/3(πr³)
(3,000)(3)=4πr²
r³=9,000/4π
r=(9,000/4π)<span>^1/3
</span> r=13.1037 m
Then, to calculate the area of the sphere, you must substitute the value of "r" into the Formula N° 2:
A=4πr²
A=4π(13.1037)²
A=2,158 m²
<span>What is the surface area of the sphere to the nearest square meter?

The answer is: 2,158 m²
Answer:
3 ≤ y
Step-by-step explanation:
-4(y-6) ≤ (-9+y)(-2)
Distribute
-4y +24 ≤ 18 -2y
Add 4y to each side
-4y+4y +24 ≤ 18 -2y+4y
24≤ 18 +2y
Subtract 18 from each side
24-18≤ 18-18 +2y
6 ≤ 2y
Divide by 2
6/2≤ 2y/2
3 ≤ y
852 and because I said so
You start off with (x)+(3x)=3675, so you can find the value of x, so you combine to create 4x=3675. then you divide 3675 by 4 to get x=918.75. then you plug them into the equations to find your numbers.
so the numbers are 918.75, and 2756.25
Your answer should be .........42.25
