An asteroid hit the earth and created a huge round crater. Scientists measured the distance around the creater as 52 km . what is the diameter of the creater ​

Answer 1

Answer:

An asteriod hit the earth and created a huge round crater. Scientists measured the distance around the crater as 52 km. then the  diameter of the crater is 16.54 kms

Step-by-step explanation:

formula to calculate the circumference of a circle is

2\times\mathrm\pi\times\mathrm r

here the circumference is given so calculate the R

R is calculated by \frac{\mathrm c}{2\times\mathrm\pi}

hence R is \frac{52}{2\times\mathrm\pi} = 8.27

diameter d is 2\times r so d= 2\times 8.27 =16.54
