10 POINTS BEST ANSWERR!!1)A photographer positions a camera on a tripod to take a picture of a grain silo.The lens of the camera is 4 feet 6 inches from the ground. To get the full height of the silo, the camera had to be positioned 18 feet from the base of the silo. How tall is the grain silo?2)A skiff leaves a dock and heads towarda house across the river. The house isat a bearing of N 64° E from the dock.
the quantity is comparable to: a million/2 * 4PIr^3/3 + h*PIr^2 (a million/2 the quantity of a sphere of radius r plus the cylindrical quantity) the place h is the top of the cylinder, no longer the silo. a million/2 * 4*7^3PI/3 + h*7^2PI = 5000 Multiply the two aspects with the help of three and multiply words out giving: 686PI + 147hPI = 15000 or 147PIh = 15000 - 686PI h = (15000 - 686PI)/147PI h = 27.813934 ft. you will possibly be able to desire to function yet another 7 ft for the a million/2 sphere on precise.
