Dani experimented with a dollar bill and the copy machine a dollar bills length is 6.1 inches and width is 2.6 inches, she reduced the dollar bill so its length was 80% of its original size. What is the length of the copy of the dollar bill? please show how you figured it out. NO LINKS

The length of the copy of the dollar bill is 4.88 inches in length and 2.08 inches in width.

Step-by-step explanation:

If Dani wants to make a smaller copy of a dollar bill and reduce its size to 80%, you will need to multiply the dollar bills original length by 8%.

80% = 0.8

0.8 x 6.1 = 4.88

80% = 0.8

0.8 x 2.6 = 2.08

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
