Answer:
Option (2)
Step-by-step explanation:
Formula to get the surface area of a sphere is,
Surface area = 4πr²
Here 'r' = Radius of the sphere
We have to calculate the surface area of a sphere with radius r = 9 inches.
By substituting the value of r in the formula,
S = 4π(9)²
Therefore, Option (2) will be the correct option.
Speed=distance/time
9:05 to 12:25 is 3 hours and 20 mins so 3 1/3 hours and the distance is 250
250/3 1/3=75km/h
