Answer:

108

Step-by-step explanation:

<u>find the volume of the cooler</u>:

V=πr²h

π×6²×16= 1809.56

<u>find the volume of the cup</u>:

V=πr²(h/3)

π×2²×(4/3)= 16.76

<u>divide the volume:</u>

1809.56/16.76= 107.969

Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.

To estimate the length of the lake, caleb starts at one end of the lake and walk 95m. He then turns a 60° angle and walks on a n
aivan3 [116]

Answer:

Length of the lake is 97.30 m

Step-by-step explanation:

We have given Caleb starts at one end of the lake and walk 95 m

So d_1=95m

And then he turns at an angle of 60°

So \Theta =60^{\circ} and then again walk 8 m

So d_2=8m

We have to fond the total length of the lake , that is d

Total length of the lake is given by d=\sqrt{d_1^2+d_2^2+2d_1d_2cos\Theta }=\sqrt{95^2+8^2+2\times 95\times 8\times cos60^{\circ}}=97.30m

So length of the lake is 97.30 m
