10 points The height of a cylinder is increasing at a constant rate of 6 feet per second, and the volume is decreasing at a rate of 171 cubic feet per second. At the instant when the height of the cylinder is 66 feet and the volume is 1254 cubic feet, what is the rate of change of the radius?

Circle a has center of (2,3) and a radius of 5 and circle b has a center of (1,4) and a radius of 10. what steps will show that circle a is similar to circle b 1) dilate circle a by a scale factor of 2 2) translate circle a using the rule (x+1,y-1) 3) rotate circle a 180 degrees about the center 4) reflect circle a over the y-axis
