Corrected question:
Diameter of the earth is 12,756 km in 1996 an new planet was discovered whose diameter is 5/86 of the diameter of the earth find the diameter of this planet in km
Explanation:
Let d1 and d2 represent the diameter of the earth and the new planet respectively.
Given:
Diameter of earth d1 = 12756 km
Diameter of new planet d2 = 5/86 of the diameter of earth
d2 = 5/86 × d1
Substituting the value of d1;
Diameter of new planet d2
d2 = 5/86 × 12756 km
d2 = 741.63 km
Diameter of new planet = 741.63 km
