Revathi reached her grandparents' place at 9:20 a. M. After travelling in a train for 9 hrs and 37 mins. What time did her train start from the station?

Starting time = 11:43 pm last night

Step-by-step explanation:

The time that her train started from the station is as follows

Given that

Grandparents reached the place at 9:20AM

The travelled time is 9 hours and 37 mins i.e. 9:37 hours

Starting time = Reached time - journey time

Starting time = 9:20 am - 9:37 hrs

= 11:43 pm last night

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
