The answer is:
The total area is:
To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.
We know that the diameter of each sphere is 7 centimeters, so, calculating we have:
Calculating the radius we have,
Then, calculating the area, we have:
Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.
So, calculating we have:
Hence, the total area is:
Have a nice day!
Answer:
t=19188.2 y
Step-by-step explanation:
The exponential decay equation is:
(1)
But, A is 10% of A₀, it means that A=0.10A₀.
If we put it into equation (1), we will have:
(2)
Now, we just need to solve (2) for t.
I hope it helps you!
