Answer:
![4\sqrt{\pi}](https://tex.z-dn.net/?f=4%5Csqrt%7B%5Cpi%7D)
Step-by-step explanation:
- The cross section of a sphere is a circle with area
, where radius is given as 4 - The cross section of the cube is a square with area
, where a is side length of square
The circle area = the square area. Thus we have:
![\pi r^2 = a^2 \\\pi(4)^2=a^2\\16\pi=a^2\\\sqrt{16\pi}=a\\ a=\sqrt{16} \sqrt{\pi} \\a=4\sqrt{\pi}](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%20%3D%20a%5E2%20%5C%5C%5Cpi%284%29%5E2%3Da%5E2%5C%5C16%5Cpi%3Da%5E2%5C%5C%5Csqrt%7B16%5Cpi%7D%3Da%5C%5C%20a%3D%5Csqrt%7B16%7D%20%5Csqrt%7B%5Cpi%7D%20%5C%5Ca%3D4%5Csqrt%7B%5Cpi%7D)
Answer:
i combined multiplied terms into a single fraction , then multiply all by the same value to eliminate common denominators simplify and divide and get x=1.5
Step-by-step explanation:
The answer is C18 because just like in algebra you'll multiply the number the two numbers in and out of the paranthisis .
Answer:
C
Step-by-step explanation:
In order to be able to find the circumference in relation to radius, you have to use the formula C = 2πr
Hope this helped :)
