55*55 = 3025 or (-55)*(-55) = 3025 which makes 3025 the square of the integers ±55, and thus a perfect square.
To calculate the surface area of a 55-gallon drum, we first need to determine the dimensions of the drum. A standard 55-gallon drum typically has a diameter of 22.5 inches and a height of 33.5 inches. The surface area of a cylinder can be calculated using the formula 2πr² + 2πrh, where r is the radius and h is the height of the cylinder. Plugging in the values for the radius and height of the drum, we can calculate the surface area in square inches.
They are: square root of 55 times square root of 55 = 55 or 27.5+27.5 = 55
55 is not a perfect square, so the simplest expression (without rounding) is the square root of 55 itself.
55 square meters = 592.02 square feet (rounded)
