The surface area of a sphere is 676cm. Determine the diameter of the sphere.

Surface Area =  46.08cm

Step-by-step explanation:

676 = 4 π r^2

676 = 4π×  r^2

676/4π =r^2

= r

23.04190006 = r

therefore diameter = 46.08380012

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

answer: (3,11) is your answer.
