Tidal power plants work best in small estuaries or inlets that border the ocean. true or false?

True

Step-by-step explanation:

The tidal ranges will be more pronounced in small estuaries and inlets because more tidal volume of water per unit area will move in and out of a small basin than a big basin (hence higher potential difference). This way more energy can be harnessed by the turbines as the tide flows in and out of the estuary/inlet.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
