Ruger has a dartboard with an area of 1600\,\text{cm}^21600cm21600, start text, c, m, end text, squared. The dartboard has a circular bullseye centered at (0\,\text{cm},0\,\text{cm})(0cm,0cm )left parenthesis, 0, start text, c, m, end text, comma, 0, start text, c, m, end text, right parenthesis. The point (\sqrt{3}\,\text{cm}, \sqrt{7}\,\text{cm})(3cm,7cm)left parenthesis, square root of, 3, end square root, start text, c, m, end text, comma, square root of, 7, end square root, start text, c, m, end text, right parenthesis is on the circumference of the bullseye. Approximately what percentage of Ruger's dartboard does the bullseye cover?

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust. 

There is no map, maybe give the link, it may be b

The answer would be c.
