Assuming the pond is rectangular in shape, therefore Volume = Width * Length * Depth
Width = Volume/(Length*Depth)
Width = 7.35/4.2*0.5 = 7.35/2.1 = 3.5 m

r= diameter / 2 = 7/2 = 3.5m
Circumference of the patio = 2*3.14*3.5= 21.98m

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Find the area per tile first:

area = length x width

Substitute the values in:

area = 3 1/8 x 2 3/4

area = 275/32

Multiply this by 9:

275/32 x 9 = 77.34375 in^2

You can round the value accordingly.

An angle measuring (525n)° is in standard position. For which value of n will the terminal side fall along the negative portion
Mazyrski [523]

For n=2,

put the value 2 in the above equation we get 525*2=1050°.

1050° angle takes 2 complete revolution and then makes an angle of 330° which will fall in the negative portion of y-axis.


For n=6,

put the value 6 in the above equation we get 525*6=3150°.

3150° angle takes 8 complete revolution and then makes an angle of 270° which will fall along negative y-axis.
