Find the missing value.
main drive gear = 45 teeth
speed of main drive gear = 450 r. p.m.
countershaft drive gear = 70 teeth
speed of countershaft drive gear (to the nearest tenth) = ? r. p.m.

i think ur answer is   (3,-1)

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
