How do you calculate surface area coverage?
Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h. In our example, the base, b, is 12 inches, and the height, h, is 5 inches. Therefore, the area is 12 inches multiplied by 5 inches, or 60 square inches.
How do we define the height of a mountain?
Heights of mountains are typically measured above sea level. Using this metric, Mount Everest is the highest mountain on Earth, at 8,848 metres (29,029 ft). There are at least 100 mountains with heights of over 7,200 metres (23,622 ft) above sea level, all of which are located in central and southern Asia.
How do they measure the height of a mountain?
To calculate the elevation of a mountain, scientists would measure the distance between two points on the ground and then measure the angles between the top of the mountain and each point. “If you have two angles, you know the third, because the sum of the angles is 180 [degrees],” Molnar told Live Science.
How to calculate the total surface area ( SA )?
total SA = 2π × 3.5 (3.5 + 5.5) = 197.920 ft 2
How to calculate the surface area of a volcano?
circular end SA = π(R 2 + r 2) lateral SA = π(R+r)√ (R-r)2 + h2 total SA = π(R 2 + r 2) + π(R+r)√ (R-r)2 + h2 where R and r are radii of the ends, h is height Paul is making a volcano in the shape of a conical frustum for his science fair project. Paul views volcanic eruptions as a violent phenomenon,…
How do you calculate the surface area of a base?
Add the surface area of the base, which may be rectangular, or triangular. To effectively work out a complex surface area, as shown left. Simply place an imaginary grid of 1” squares over the part, and count the whole squares. Then go around the perimeter and add up all the squares that are more than ½ full.
Which is the correct definition of specific surface area?
Specific surface area (SSA) is a property of solids defined as the total surface area of a material per unit of mass, (with units of m 2 /kg or m 2 /g) or solid or bulk volume (units of m 2 /m 3 or m −1).
