A cylindrical container of three rubber balls has a height of 18 centimeters and a diameter of 6 centimeters. Each ball in the c
ontainer has a radius of 3 centimeters. Find the amount of space in the container that is not occupied by rubber balls. Round your answer to the nearest whole number.
The formula for to find the area of a cylinder is 2*3.14*r*h+2*3.14*r^2 so the area of the cylinder is 395.84 cm. To find the area of the balls, which are spheres, is 4*3.14*r^2, which equals a total area of 113.1 for one ball. Multiply that by 3 because there are three balls. That'll give you 339.3. Now you'll do 395.84cm-339.3cm=56.54. Now round that to the nearest whole number which will give you 57. The answer is 57cm.
The tangent line to a circle makes an angle of 90 degrees with the radius. If |FG| is tangent to circle E. then 30^2 = 26^2 + 17^2 which is not true. Therefore, line segment FG is not tangent to circle E.
You have to start at the 3and rise all the way to the 8 which is 7 and then run which is 3 so the slope mx is 7/3x. To find b which is the y intercept find the point where the line hits the y-axis.
