Spherical ball of lead has a diameter of 5.5 cm . what is the mass of the sphere if lead has a density of 11.34 g/cm3? (the volume of a sphere is (43)πr3 where r is the radius.)

Hope my answer would be a great help for you.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

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
