4.The side of a square plot land is of length 20m. Find the cost of fencing the plot at the rate of Rs. 10 per meter.​

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

49/6 is going to equal 8 1/6
