The length of minute hand of a clock is 5.4 cm. What is the area covered by this in 10 minutes
Read Solution (Total 9)
-
- area of circle is pi*r^2
but in 10 minutes area covered is (10/60)*360=60 degree
so formula is pi*r^2*(angle/360)=3.14*(5.4^2)*(60/360)=15.27 cm^2 - 10 years agoHelpfull: Yes(31) No(1)
- 4.86*pi cm square
Angle made in 10 min = 10/60*360
=60 degree
Area of sector = n/360*pi*r^2
=60/360*pi*5.4*5.4
=4.86*pi cm^2 - 10 years agoHelpfull: Yes(5) No(1)
- A=n/360*(3.14*r*r)
r=5.4cm
n=60 degree
A=15.26 sq. cm
i guess please confirm from others

- angle made by minute hand in 10 minutes is 60 degree.
hence area=3.14*(5.4)^2*(60/360)=15.3 cm^2 - 10 years agoHelpfull: Yes(2) No(0)
- 4.86 pi cm^2
(angle/360)*(pi)*r*r
angle covered in 10 minutes is 60
pi*r*r/6 - 10 years agoHelpfull: Yes(1) No(0)
- area of dial=pi*r*r;
i.e pi*(5.4)^2
area covered in 60 min=pi*29.16
in 1 min= pi*29.16/60
in 10 min=(pi*29.16/60)*10; - 10 years agoHelpfull: Yes(1) No(0)
- pi*(r^r)*(60/360)
area=pi*(5.4)^(2*60) - 10 years agoHelpfull: Yes(0) No(0)
- area=pi*(5.4)^2*60/360
=pi*(5.4)^2/6 cm^2 - 10 years agoHelpfull: Yes(0) No(0)
- why it is angle/360????????
- 10 years agoHelpfull: Yes(0) No(1)
