![]() According to the Electric Reliability Council of Texas (ERCOT), the Texas power grid was "seconds or minutes away from" complete failure when partial grid shutdowns were implemented. ![]() Damages due to the cold wave and winter storm were estimated to be at least $195 billion, likely the most expensive disaster in the state's history. federal regulators ten years earlier that had warned Texas that its power plants would fail in sufficiently cold conditions. ![]() The crisis drew much attention to the state's lack of preparedness for such storms, and to a report from U.S. Deregulation of its electricity market beginning in the 1990s resulted in competition in wholesale electricity prices, but also cost cutting for contingency preparation. Texas's power grid has long been separate from the two major national grids to avoid federal oversight, though it is still connected to the other national grids and Mexico's the limited number of ties made it difficult for the state to import electricity from other states during the crisis. Data showed that failure to winterize power sources, like wind turbines and natural gas infrastructure, had caused the grid failure. State officials including Republican governor Greg Abbott initially blamed the outages on frozen wind turbines and solar panels. At least 246 people were killed directly or indirectly, with some estimates as high as 702 killed as a result of the crisis. More than 4.5 million homes and businesses were left without power, some for several days. The storms triggered the worst energy infrastructure failure in Texas state history, leading to shortages of water, food, and heat. Calculate its volume and surface area.Ĭalculate the area of a regular hexagon if the radius of the circle circumscribed is 6.8 cm.Ĭalculate the volume and surface of a regular hexagonal prism with a base edge a = 30 m and a side edge b = 50 m.In February 2021, the state of Texas suffered a major power crisis, which came about during three severe winter storms sweeping across the United States on February 10–11, 13–17, and 15–20. The regular quadrangular prism has a base edge of 7.1 cm and a side edge of 18.2 cm long. Find the volume and surface of the prism. The prism's base is a regular hexagon consisting of six triangles with side a = 12 cm and height va = 10.4 cm. Determine the radius of the circle inscribed in this triangle.Ĭalculate the volume and surface in the shape of a regular hexagonal prism with a height of 1.4 m, a base edge of 3dm, and a corresponding height of 2.6 dm.Ĭalculate the regular hexagonal prism's surface whose base edge a = 12cm and side edge b = 3 dm. In a regular decagon, the diameter of the circumscribed circle measures 10 cm. The regular hexagonal prism has a surface of 140 cm² and a height of 5 cm. The radius of the bottom of the cylinder is 10 cm.Ĭalculate the volume and surface of a regular hexagonal prism with the edge of the base a = 6 cm with the corresponding height v1 = 5.2cm and the height of the prism h = 1 dm. Determine the volume of the regular triangular prism inscribed in the cylinder. ![]() The shell of the rotating cylinder is four times larger than the contents of its base. What is its volume?Ĭalculate the surface area of a regular hexagonal pyramid with a base inscribed in a circle with a radius of 8 cm and a height of 20 cm.Ĭalculate the volume and surface of a regular hexagonal prism with a height v = 2cm and a base edge a = 8cm. The tops of the base of a regular hexagonal pyramid lie on a circle with a radius of 10 cm. Calculate the volume and surface area of the prism. The radius of the circle of the described base is 8 cm.
