answer 1= if sector makes 60 degree angle then it must be equilatorial triangle.
then using herons formula its area can be find.
answer 2=Find r through cirmcumference then find area.
answer3=the angle swept by minute hand in 60 min=360
in 5 min=6×5=30 (unitary method)
now find area.
Note= i have not given full answer because that is spoonfeeding i have given u hints these are enough to solve them.

HEY MATE,
STEP BY STEP
FIRST WE NEED TO UNDERSTAND SOME BASICS FOR QUESTION - 3.
1) FORMULA = SO IN THIS QUESTION WE NEED TO FIND AREA OF SECTOR WHICH = πR^2XΦ/360
2) WE NEED TO KNOW HOW MUCH DEGREES IT COVER'S IN ONE MINUTE.
MINUTE HAND COVER = 360/60
= 6 DEGREES IN ONE MINUTE.( NOTE THIS IS APPLICABLE FOR SECOND HAND AND HOUR HAND ALSO).
Q-3/ANS
THE AREA SWIPE BY MINUTE HAND IN FIVE MINUTE = 6 X 5
= 30.
=πR^2Φ/360.
= 22/7 X 14 X 14 X 30/360
= 22/7 X 14 X 14 X 1/6
= 22 X 14 X 2 X 1/6
= 154/3CM^2.
I HOPE THIS WILL HELP YOU...
PLS MARK AS BRAINLIEST.
