Answers
Given : Shivam travel from P to Q via O on motor bike in 3 days
and Travel from P to Q via R by car in remaining 3 days
Radius = 4.2 km central angle = 60°
To Find : The total distance travelled by Shivam through the motorbike in a week to go school is
Solution:
P to Q Via O = PO + OQ = 4.2 + 4.2 = 8.4 km
Then returning back via same route = 8.4 km
Hence Distance in 1 day = 16.8 km
Distance in 3 days = 3 * 16.8 = 50.4 km
Additional Info:
Via Car = P to Q Via R = (60/360)2πr =
(1/6) (2)(22/7) * 4.2 = 4.4 km
in 1 day = 2 * 4.4 = 8.8 km
in 3 days = 3 * 8.8 = 26.4 km
Area of sector POQ = (1/6)πr² = 9.24 km²

The cardboard shows me how it was
When the two girl cousins went paddling
Each one holding one of my mother’s hands,
And she the big girl - some twelve years or so.
All three stood still to smile through their hair
At the uncle with the camera, A sweet face
My mother’s, that was before I was born
And the sea, which appears to have changed less
Washed their terribly transient feet.
