A fence is to be erected around a circular field the cost of fencing comes to rupees 2640 @ rupees 12 per metre find the radius of the circular field
Please answer fast
circumference of circle * cost per meter = 2640
2* pi * r * 12 = 2640
r = 2640 / (2*12*pi)
r = 35 meter
My is coming 3.5 how?
Oh sorry it is right
Thank you
okay
any other questions?
A piece of thin wire is in form of an equilateral triangle of side 8.8 DM is bent into a circle with no loss in wire find the diameter of the circle
This one please explain
please send image of complete question
okay for 10th question proceed like this
(pi*D)/2 + D = 108
now solve for D
you will get D = 42 cm
Yes
Next one
answer for 12th
Thanks
The last one
for last one
r = 11 cm
so in 1 hour the minute hand will complete 1 circle so calculate circumference
C = 2*pi*r = 2*3.14*11
for 2 hours multiply C by 2
so you'll get C = 138.16 cm
