<span>Using the formula 1/2*b*h for the area of a triangle, we get 7.8 cm^2 as the area of the base. Now let us assume that the three faces of the pyramid are of the same dimensions. So by subtracting 7.8 from the total surface area and dividing by 3, we get a face area of 29.6 cm^2. We get a height of 19.73 cm (using a "base" of 3 cm). Using half of the face of the pyramid (a right triangle) and applying some trigonometry (19.73 cm/sin 60) we get 22.78 cm as the slant height of the pyramid.</span>
I Think it’s 3 or that’s what I got
A comet is a smaller celestial body orbiting the sun, often with a tail made of debris. Debris from a comet can turn into a meteor, which means that is has entered into Earth's atmosphere and burns due to the friction with the Earth's atmosphere. If a meteor is large enough, it can survive this fall into Earth's atmosphere and strike the Earth, on land this would leave an impact crater, or a collision site where the meteor met the surface. This can also happen in water, but may be difficult to see and may not leave an impact crater. Simply, Comet to Meteor to Impact crater.
Answer: Dunes are formed through the interaction of mountains and wind. The wind picks up quartz grains from the mountains in the area to form the dunes and these are reshaped by the same process over time.
