Answer:
r ≅ 3.00
Step-by-step explanation:
First we need to get the formula for finding the volume of sphere. The formula is:

Now to find for the radius, we need to input the value that we know into the formula.

Now we multiply both sides by 3/4.


Now divide both sides by π.


To find r, we finally get the cube root of both sides.
![\sqrt[3]{r^{3} }= \sqrt[3]{27.01}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E%7B3%7D%20%7D%3D%20%5Csqrt%5B3%5D%7B27.01%7D)
r ≅ 3.00
Answer:
Astrid needs 280 tons of wood to build ships that can accommodate 2100 sailors
Step-by-step explanation:
Here, in this question, we want to know the amount of wood needed by Astrid to accommodate 2100 sailors.
From the question, we can see that 40 tons are needed to build a ship that can accommodate 300 sailors.
Now, we want to make a calculation for the amount of wood needed for 2100 sailors.
Let’s have it this way;
40 tons = 300 sailors
x tons = 2100 sailors
So mathematically,
x * 300 = 2100 * 40
x = (2100 * 40)/300
x = 280 tons of wood
We can see that 280 tons of wood are needed to build ships that can accommodate 2100 sailors
