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
(-x-1)(x-1)(x^2+6)
distribute from there i think?
math papa website can help with this... im not that good at math
Answer:
33.3% probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone.
Step-by-step explanation:
In this problem, we have these following probabilities:
A 60% probability that a customer purchases a waffle cone.
A 20% probability a person person purchases both a waffle cone and two scoops of ice cream.
Based on the average daily sales from last week, what is the probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone?
This is 0.2/0.6 = 0.333 = 33.3% probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone.
We know the rate of the change, 3 meters per hour. And we want to know how long it will take to reach 12 meters. Say we need to reach 6 meters instead 12.
How long will that take? 2 hours! Because we divide 6 m by 3 m/h.
Now let us do the same thing will 12 meters.
12 m / 3 m/h = 4 hours
It will take 4 hours to reach the 12 meters height.
