Area = (√3/4) * a2You can also use the side length to find the height (h) or the inradius (r) of the triangle:h = (a√3)/2 r = a/(2√3)If you know the area of an equilateral triangle, you can use that information to find the length of one side (a) using this ...
Cross-sectional area - cross section - slice plane Now there is the question: How can we calculate the cross sectional area (slice plane) A from the wire diameter d and vice versa? Calculation of the cross section A (slice plane) from diameter d: r = radius of the wire d = diameter...
A circle of diameter 13 cm has a chord length of 12 cm. Calculate the shortest distance from the centre of the circle to the chord. The length and width of a right triangle are 6.5 cm and 4.5 cm. Find the area and perimeter of the triangle. ...
