Answer:

2950 m

Step-by-step explanation:

The radius to which the sun must be compressed to become a black hole is equal to its Schwarzschild radius, which is given by the formula:


r=(2GM)/(c^2)

where

G is the gravitational constant

M is the mass of the star

c is the speed of light

For the Sun, its mass is


M=1.99\cdot 10^(30)kg

Therefore, its Schwarzschild radius is


r=(2(6.67\cdot 10^(-11)Nm^2kg^(-2)(1.99\cdot 10^(30) kg))/((3\cdot 10^8 m/s)^2)=2950 m
