A well of diameter 4m is dug 14m deep. The earth taken out is spread evenly all around the well to form a 40cm high embankment.

dimulka [17.4K]

Answer:

82.72m

Step-by-step explanation:

Volume = πr2h

= 3.142*7*7*14

= 2,155.41m³

Now that we hav the volume of earth, we go on to find the raduis of the spread

2155.41m³ = 3.142*r²*0.4

2155.41m³ = 1.26r²

r² = 1,710.64

r = 41.36m

Width = diameter = 2r = 82.72m

a circle has a center at (3,5) the point (3,8) is on the circle what is the circumference of the circle to the nearest tenth of

kogti [31]

You need to use the distance formula to find the radius of the circle.

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2} \\ \\ d = \sqrt{(3-3)^2 + (8-5)^2} \\ \\ d = \sqrt{0^2+3^2} \\ \\ d = \sqrt{9} = 3$

The radius is 3.

The circumference is $2 \pi r$

$= 6\pi \\ \\ =18.8$
