Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height. SA = 4πr2. Find the area of the great circle and multiply it by 4. SA = B + πrS.
WebBecause the area of an equilateral triangle is ¼ a²√3. Since a = r√3 also stated as a² = 3r². Substituting, πr² - ¾r²√3. Since r = 2, we get 4π - 3√3 = 7.370. Of course my way does require knowing that a² = 3r² for an inscribed equilateral triangle (though it isn't too hard to derive if you didn't know that) Comment. the prestwick mortgage groupWebFeb 20, 2024 · I did some research and found the following formula to calculate the diameter (distance between the circumcenter and one of the vertices): $$ \frac{abc}{\sqrt{(a + b + c)(-a + b + c)(a - b + c)(a + b - c)}}$$ ...
