Answer:
3.167353103 meters
Step-by-step explanation:
The volume of a sphere can be found using:
v=4/3πr^3
We know that 133.1 is the volume, so we can substitute 133.1 in for v
133.1=4/3πr^3
To solve for r, we need to get by itself. First, divide both sides by 4/3π
133.1/ 4/3π= 4/3πr^3/ 4/3π
31.7752843883=r^3
Since r is being raised to the 3rd power, take the cubed root of both sides
![\sqrt[3]{31.7752843883}=\sqrt[3]{r^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B31.7752843883%7D%3D%5Csqrt%5B3%5D%7Br%5E3%7D)
3.167353103=r
So, the radius is 3.167353103 meters
200 is 1/10 of 2,000.
because it is 1/10 you times it by ten.
200×10= 2,000
Answer: D
Step-by-step explanation:
(x-9)² = x-3
(x-9) (x-9)= x-3
x² - 9x-9x +81 = x-3
x² -18x+81 =x-3
x²-19x+84 =0
(x-12)(x-7)=0
x=12 or 7
