- 7) Find the area of the surface when y = Vx, from (4, 2) to (9, 3) is rotated about the x-axis. %3Darrow_forwardThe Deligne Dam on the Cayley River is built so that the wall facing the water is shaped like the region 0.6x² and below the line 2 above the curve y y = 280. (Here, distances are measured in meters.) The water level is 34 meters below the top of the dam. Find the force (in Newtons) exerted on the dam by kg m³ = water pressure. (Water has a density of 1000- and the acceleration of gravity is 9.8 m sec² .) " Note: Weight density of water is 1000 (9.8)=9800 N/m^3arrow_forward
