Answer 1

Hi,

9:00 to 9:30 is 180 degree

180/6 = 30 degree is 9:30 to9:35.

Thetha = 210

Area = 210/360×22/7×7×7

21/36×22×7

21/36×154

21/18×77

1617/18

89.833 sq. cm

I hope you have understood it.

Answer 2

Answer:

Step-by-step explanation:

Angle of 1min= 360/60=6degree

So angle of 35 min

35x6=210degree

So area of sector= theta/360 X Pai r²

210/360 X 22/7 X7 X 7

7/12 X 22/7 X 49

1/6 X 11 X 49

89.83cm²
