Question

answere the question ....class10answere from 1 to 3

Answer 1

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.

Answer 2

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.
