For 12 to 19, decide if each figure is the line symmetric. Draw and tell how many lines of symmetry each figure has.

9514 1404 393

  12: 1; 13: 3; 14: 2; 15: 1; 16: 1; 17: 6; 18: 0; 19: 4

Step-by-step explanation:

12. 1 line, down the center of the middle bar.

13. 3 lines, each through the center of a short edge and the center of the opposite long edge.

14. 2 lines, one along each axis of the ellipse.

15. 1 line, along the stem. (The picture is distorted enough it is hard to tell if there is any symmetry.)

16. 1 line, perpendicular to the base at the center.

17. 6 lines, 3 along the stems, and 3 between the flowers--all through the center.

18. 0. The figure has no symmetry.

19. 4 lines, all through the center. 1 vertical, 1 horizontal, 2 at 45 degree angles to the vertical.

The Line symmetric are 14,15,16,17, and 19

Step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

50
