The mass of a freight train is 9.98 • 10^6 kg the mass of an aircraft carrier is 7.3 •10^7 approximately how many more kilogram is the mass of an aircraft carrier than the mass freight train ?

63'020'000 kg or 6.302 × 10^7

Step-by-step explanation:

Freight train = 9.98 • 10^6 = 9'980'000 kg

Aircraft carrier = 7.3 •10^7 =73'000'000 kg

Thus 73000000 kg - 9'980'000 kg = 63'020'000 kilogram =

= 6.302 × 10^7

(scientific notation)

= 6.302e7

(scientific e notation)

= 63.02 × 106

(engineering notation)

(million; prefix mega- (M))

= 63020000

(real number)

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

i think it would be 42cm
