I have a magical machine that can scan a 3D object and determine whether the numerical value (in units) of its surface area is equal to the numerical value (in units) of its volume. After experimenting with different objects in my lab, the only thing that the machine gives an output of is my spherical ball.
What is the radius of my spherical ball (in units)?
+1005 So essentially
4πr^2 = 4π (r^3/3)
r^2 = r^3 /3
r^2 *3 = r^3
3 = r
Feel free to ask if you don't understand anything!
