For a circle with the given circumference of c, find the radius and diameter.

c=25 cm

r=39.27

d=

Step-by-step explanation:

C=2pi(r)

25=2pi(r)

25/2pi=r

25/2pi=39.27

r=39.27

d=2r

d=2(39.27)

d=78.54

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
